Cool... I don't think we've had something like this asked.... I could have missed it though!
Me? Hrmn... I have to admit I'm a bit impish when it comes to letting out the "inner child" - I loooove LEGO and Brio, I adore fingerpainting and blowing bubbles and my rubber duckies in the bath!
I race, I splash in puddles and I ping stuff I really shouldn't - the occasional rubber band for instance
I run down supermarket aisles with a trolley and lift my feet up (and pretend it wasn't me when I crash), I walk on walls and very occasionally I hopscotch the zebra crossings just to annoy the drivers. Or when I think no-one's looking. Oh and today I was looked at funny for swinging on the scaffolding attatched to the front of the TESCO's building
Woops! Wasn't me!
