rudeness

OK so how can ppl be so rude. I have this class and i took it because the teacher i like how she teaches and everything. i just don't under stand how ppl in there can be sooo rude. There is a kid in the class (when he decides to show up) is the to good for you attitude and gives nothing but rudeness flows out of his mouth he even gives shitty looks. So last night in class i was waiting in line to get my papers graded and so its was my turn and he kids goes I thought i was next ed with this smarty ass tone and i said back in the same tone well no i was standing here and he says oh well i didn't see you. I mean I know i am short but come on dude i am not invisible get out of you little bubble and realize there are other ppl in class. And then the teacher was tring to help this girl get a better grade on her test trying to help and the girl turns around and give the dirty look that could make ppl think twice and there is a group of girls who just talk and talk and talk and sometimes over the teacher. to top it all off there is a guy who trys to go though the teachers files and is a smart ass. Its sooo rude I really don't understand how ppl can be so rude you are in a collage class not in high school which isn't right to do anyways but its time to be grown ups and act like it. i mean you can tell the teacher is stressed and has a lot of her plate and a class that doesn't shut up and over powers the teacher isn't fun. When we test shut the hell up be polite to others in class. wow i feel better. VENTING IS GREAT.
