I was always bored come Christmas day. Presents were bought really early by mum n dad and were kept in the top of their wardrobe. Around September time I would find these, play with them regularly when they were out, and re-package.
If it was an electrical game/toy I would take it round to my mates and charge them a few pence a go. The parents could never really understand why I could play these toys on Christmas day and never needed to look at the instructions. Faking excitement on Christmas Eve was a bummer tho. I still carry that guilt.
