My internship is in Paris and we're having a suffocating time. Right now there are storms but in less than half an hour afte the rain, we're back to suffocating heat again. I'd die if I had no air conditioning at work!
Your trip to London sounds like a blast. My policy when it comes to visiting a new town is not to run from a site to another one in the shortest of times possible, but rather to walk and just feel the atmosphere of it, the way people have fun
, etc. London is so much more than a bunch of cathedrals, I really do hope I get to see it properly one day!
