It takes courage for a guy to ask you out, so even if you're not into him, it's best to let him down gently. At the same time, you have to be straight with him. (Stringing him along is just torture.) Just tell him he's a really nice guy and you're flattered that he asked you out, but you'd rather just be friends. Like ripping off a bandaid as gently and sweetly as possible.
