I have two people like this, my friend from a while ago, and her sister. My old friend thought she was great at art, when I actally cringed every time I saw her drawings. She would also sing in this bad voice because she thought she was a good singer. Her sister on the other hand... she thought she was good at EVERYTHING. She awas also a nationalist....This ***** was really proud to be American because she thought every other country sucked and the people from the other countries were idiots
