So... my brother has had this friend for years (let's call him D) and my brother turned 18 last year and moved out. I always thought D was cute.. well recently he's been showing up to our local basketball gym and my mom works there, I always come on sundays with my cousin when they have a basketball game.. D plays and like i realize how much I actually think he's cute and I sorta like him. I'm 20 he's 18 and I'm scared/nervous to death to even say hi to him. I don't know what to do
