To my surprise Ada, the 2nd Giant Tunnelling Machine of Doom, has already disappeared from view and is presumably tunnelling its way towards east London. This presumably means I've fallen into a parallel world where things work efficiently. As support for this I saw an airship in the distance (OK, one of the Goodyear blimps), which is supposed to be one of the signs you're in a parallel world. Unfortunately it was out of sight by the time I got home and got my camera - so it goes.
Weather was lovely walking home, but has rapidly turned dull and is allegedly going to be crap from now until the weekend, which probably buggers my plan to take pictures of the Trooping the Colours flypast - it was already a bit difficult because I'm supposed to be helping someone do a flat swap, I'll just have to see what happens.
