I got a pair of roller blades recently. It's a LOT of fun. I might have zoomed by you in Battersea Park without realising it. I just need a classic Walkman to listen to while I blade and I'll look like a true 90s douche.
I'm really into cooking and baking and have tried out some pretty awesome recipes (with varying results). My repertoire now includes (but is not limited to) cinnamon buns made (in part) using mash potatoes, experimental onion pasties and boiled pretzels.
And finally, I get excited about things that most people would probably think aren't that exciting, like Big Ben reading 11:11 on the 11th November 2011. That was an amazing day and I'm sad that it can never happen again.
