Well, it could be a lot of things, but if you're Sophie or Juliette or pretty much any tween, starting a new sticker collection is guaranteed to bring on some big grins!
They've been collecting for a few weeks now and get really excited every time I relent and buy them a pack on the way home from school or give them some pocket money so that they can run off to the shop and buy some !
So can you guess which collections have got them so obsessed?
It's One Direction for Sophie. (No prizes for guessing that one !)
And Monster High for Juliette. (That was a pretty safe bet too !)
I still remember my Smash Hit sticker album back in the 80's - it would be hilarious to look back through that now !
