i think your a bad dad..
this is like your 294920 question about parenting
and honestly..
there all really dumb questions.
Did he give you a thumbs down for that?
BTW, your last question rattled a few nerves, didn't it? lol!
let your kid be whatever he wants!!! this is his holiday and you cant blame him for having a imagination!!!
Why did you say no? (what reason). Well, I think your son should be what he wants for Halloween next year.... he only has a few more years to dress up anyways... hey, why not make a memorable Halloween for him?? I'm sure he'll remember after a couple of years when you let him be a troll.
