To the OP. There are a lot of jerks in this world. It wouldn't surprise me of that is a 'thing' to do to people on there. To purposefully open windows and call people ugly and close out. Just for laughs. People are becoming more and more mean spirited and vile now that they have the luxury of hiding behind keyboards and no longer have consequences for their words.
Really, if that's the worst you've gotten, consider yourself lucky. I've seen people half your age spoken to in much, much worse a manner, for doing nothing more than being themselves.
