Urban squirrel

Spoke to my Mum and my sister on my way into work today - had a good old catch up with them both :)  On my way home, I surprised this little squirrel on the wall along the Barbican highwalk.  I wish I'd got a photo when it first saw me - it ducked down the other side of the wall, with just its little paws and the tip of its tail showing.  Very cute.  It then popped its head back up for another look at me, got curious when it saw me pointing my camera at it, then moved in a bit for its close-up!
