So I never did a Christmas list growing up. We got what we were given! But, DC6 has got the idea from somewhere and has put on it things he's seen or heard of that I can't actually get. He is saying Santa's elves can make absolutely anything so he sees no reason he won't get them. Last year he was proudly announcing to his class that Santa wasn't real so I'm guessing the promise of impossible toys has changed his mind?! 
Anyway what should I do about these impossible items? Do we just post the list off to Santa and say "wait and see" ? I feel like he won't drop it and Christmas day will be fairly ruined with him being disappointed/sad and not appreciating anything he does get. Help!!
