DS1 (16) says it's his favourite bit of Christmas
Ds2 looked horrified when i said jokingly that maybe they're a bit old for them now? 
I never had one as far as I can remember? Mine always have.
It's getting hard to find ideas as they age though but I've got a few. They both like apples and nuts so can shove some of those in too. Chocolate and bits and bobs plus novelty gifts.
DS1 only asked for 2 things for his main presents and they're no more than £50 in total. I'll get him a new dressing gown etc.. too.
