What would you do, if someone upset your Happiness?

I don't let anyone affect my mood in a radical way: people might upset me (and they do) but just for a few minutes;) if someone does or says something that upsets me I express my discontent, argue with them if necessary, and then I just go back to normal;) as for pretending everything is OK, that's just not my cup of tea: I never lie/pretend anything, if I don't like something/someone I always make it very clear.

The first thing I do when someone trespasses upon me is: I reflect on whether they have a reason to trespass upon me: whether I have done something to hurt this person so that this person wants to hurt me. If that is the case: I apologize and restitute or compensate the pain I have caused.

Now, if the person wants to hurt you without any reason, you must defend yourself: you cannot allow someone to trespass upon you ... unless they are unredeemable lunatics incapable to think rationally ... in that case, you run away.

When we pretend we hide our feelings; when we are happy show it when we are sad show it because if you don't they will just try to make you unhappy until they can see the unhappy in you; they are unhappy why can't we all be unhappy like they are is what they think; i think.
