What will you say when a girl ask you this Give me one reason yy l shld be interested in u?

You can answear to her if you really like her by this: "You don't have to be. But tell me, if you wanna go to the pool what's you first thing to do? To buy a slips or go with underwear? So give me a chance, if you don'thave interesd to me then i'll go". Or something like that. That question my friend is a both very simple and very hard to answear debending on the situation. If a can say one more thing:
If the girl gives a chance to you, don't waste it, but if the girl doesn't do that, be a man. :)
