water skiing team practices? There is a team for that? wow.
Anyway, calm down and think, how do you like to be treated? Most of us want someone who is pleasant, interested in us and willing to talk. That's the basics for friends or dates. There is no magic wand or formula to follow from there. I've known guys for 4 months before they asked me out and I've had guys ask me out minutes after meeting me and of course the much larger group of men who had no clue I was on this earth ....couldn't tell you what I did different since I tend to act the same all the time.
My advice, relax, enjoy yourself, you are in college (one of my faverate places in the world) and don't worry, you will figure out what to say without pushing so hard to sound smart (or sassy or sexy or flirty or whatever you are going for)
