if he is a girl then he lied about his gender cause he didnt want to go out with this guy, but after that he said its a lie cause he wanted to be friends with him and its a really cruel thing to do, so if he is a girl he is a trash
if he is a boy then he told truth about his gender cause he wanted someone to know - he wanted a true friend, but he said it was a lie cause the guy wanted to leave and wanted to keep him with him since he already told him he is a guy - the guy could tell all school about this and his life would be over - so yeah, he is a trash anyways
