will I look stupid when I go to the principle?

Yes,

Your no longer stupid - that's in basic terms which you don''t comprehend. stop questioning complicated, think of undemanding. Now ignoring the vertical pipes, in any hydraulic gadget, water pipes, crude oil strains, and so on. and so on. while the liquid flows although the gadget there's a organic 'tension' drop from the source to the outlet. that's simply by inner and pipe wall frictional outcomes and a few different issues, in smaller pipe diameters that's greater substantive. If the pipe become 20 km long there could be enormous distinction in tension from one end to the different. So, steadily bit via bit the stress reduces as much as the outlet the place it turns into 0. So, even from a million cm to the subsequent cm down the pipe there's a tension distinction, an exceedingly very small one in spite of the incontrovertible fact that that's there. So for this reason you spot at component A that the stress is greater than component B and so on. On our crude oil pipeline we've a tension drop of approximately 8 bar (a hundred and sixty psi) over 7 km Now slightly greater - In moving liquid the 'tension' is made up of three aspects a million) the stress created via the dynamics of the pump impeller or piston, power conversion; 2) the 'head' i.e. height of the liquid 'static' tension and 3) the fee tension - that's the stress you may sense in case you place your hand in front of the outlet. that's Bernoulli's equation. i.e. all 3 upload up and = a relentless in a flow line. yet differently to think of approximately that's to imaging a backyard hose with 3 holes in the hose wall like the diagram; now water flows from the faucet and reaches the 1st hollow and of direction some water 'leaks' out reducing, or relieving, the stress, something includes directly to the subsequent hollow however the stress is decrease so would not spurt out rather as extreme, and so directly to the final hollow and then out the tip. we could pass on the clarify greater with reference to the static head tension yet perfect to stop here for now, so meanwhile wish this user-friendly explanation will coach you a thank you to greater suitable comprehend the gadget - save issues undemanding.

Honestly he doesn't seem like stalker. For someone to be a stalker there is to be a long history of the stalking. It only becomes stalking once it goes on for a period of time.

As for the principle you may not want to go to him or her. I'd suggest the guidance counselor. Just express you feel uncomfortable. If this did turn into stalking you would have a record of your early complaint.

Also there is no need to apologize. This is the whole point of this site to ask for help and receive it. No one should ever have to apologize for using this site properly & asking or giving help.

EDIT - Have you blocked all of his calls so he can't text you anymore? I would do that too.

Some parents may say you are going over board but as a mother I am telling you that you are doing the right thing.

I ignored a lot of my stalkers warning signals. Things turned really bad to me. Some user said my past was "disturbing" & they are right. It is but if my past can help others then I am going to share it. If you don't like it then don't read it. But my stalking into rape and what the police said was kidnapping since I was lied to where we were going. I met him online. He was not 19. He was in his late 20s. It took me 10yrs to report it.

You are doing the right thing. It will be wonderful if you are wrong or making a mistake. But wouldn't you rather be careful than stupid?

I'd also suggest you request classes changes for HIM. You shouldn't have to move. As a kid in jr high I had a bully who was just horrible to me. Our principal changed all this girls classes so I wouldn't see her at all during the day & even lunch.

No you wont look stupid! I've had a similar experience but I didn't go to the principal. I told him straight up that he was getting weird and said I didn't want to be friends if he continued what he was doing. He was smart enough to stop tho. Since your "stalker" isn't backing off going to the principal is the right thing to do.

It's principal not principle and yes you are doing the right thing because arm carving is not normal and is in fact particularly adnormal.

If hes persistent, take it to the police. I know how you feel the same thing happened to me( minus the arm part) i slapped across the face when he got too close to me and started licking his lips. Dude, next thing you know he shows up at your house ready to rape you. Its all downhill from here

Yeah! Thats just too freaky!
