bad: a pigeon slammed into my 2nd floor window (while i was sitting inches away) and fell to the ground.
good: half an hour later, when i got brave enough to look, I opened up the window to hang my body halfway out to see if i could see its poor wee body lying on the pavement, and there was a huge blast of THUNDER, which I love! Might not have heard it as well through the double-glazing, but at that exact moment, I was hanging out the window! (the pigeon's body is not there...)
