Older brother's friend asked me out? i think?

Not all nice guys are really that nice. Sometimes they're trying to win your affection because they've got this intention of getting to know you until it steps up to another level and so on. And when the time comes that they're so done to you, they just throw you away like a garbage and you feeling so miserable and think life has cheated you, don't be that kind of girl. I know he's nice and everything but don't give all of your trust. Save some for yourself.
