So today one of my roommates and I were talking about one of our mutual friends. We'll call him "tim". We were talking about how tim is so complelty oblivious to women when they are attracted to him. I've hit on him once or twice at our place when we have people over, and he doesn't know what is going on. One of my other roommates said that at this one formal she went to, there was about 3-4 girls dancing around him, and he did not see that these girls are attracted to him. How do we let him know and understand that he is an attractive guy and everything? He is so helpful too since my roommates and I have computer troubles, well me more than them. He fixes/looks at them for free, not wanting anything in retrun. How do we let tim know that women like him?
