questions

I am aware I don't "own" any of the lunch tables at school but I have been sitting at one particular lunch table for the past 3 years with my friends (I'm a senior). I am at a very high populated high school so people have tried to take it before but they've given up after they've seen I will sit there whether they're also there or not because I refuse to give it up. I am a very stubborn person and giving it up IS NOT an option.

There is a group of about 10 people who started sitting there last week, and they don't have a third period so they get there before us. They're extremely loud and rude; I also left my backpack on the table to go get lunch and my front pocket was open. It's not that I own the table, it's just that it's common sense and common courtesy not to take someone's table. It's kind of like an unspoken rule. And there is nowhere else for us to sit but these people have friends right across from us they could easily sit with. Now a lot of my group of friends have to stand all of lunch to be able to be with us and there's nowhere else we could all go.

This may seem so petty and stupid to some of you, but I am very stubborn and very determined not to let these rude, disrespectful people get what they want. I'm not mad that it's "my table", I'm mad because of how these people are acting.

PLEASE HELP ME! What the hell do I do?!
