He wasnt like his brothers...who kept asking me when r we gonna f***.But dustin would sit on the bench, and while i was standing up try to get my attention....Plus, he asked if i was walking home....i said yea jus to c wat he'd say. and he said he'd walk me home.even tho he lives far from me.After he said that, i joked around and said ur gonna me, then he said "naw i would never do that, i just wanna get to kno u.does he like me?
