I want him to get the message that I don't like him.
There's this guy who flirts with me all the time but I don't like him. One of his friends told me that he likes me but I honestly find him a bit of a show off. In front of me he keeps doing those weird hair flips and he says really loudly to his friends: "I ran like 2 miles yesterday, and my feet still ache." And he always tries to impress me in gym class and stuff like that. But I want him to get the message that I don't like him and I don't want to say it outright because he's super sensitive.
