if he asked me to help him attatch a jet engine to his car, I'd probably help him with that too. It's up to him to figure out if he really wants/needs to do it, and he might have 1000 reasons that he doesn't wanna explain here.
if someone asks me for the weather section of the newpaper, I give them the weather, not the weather, aswell as sports and politics, just incase they where interested.
and after 2 full pages of responses, noone had handed him even the weather page yet, just sports.
