I just got done washing my bedroom windows. This involves climbing out on the second story roof for the one big window but since the roof is slanted at a slight angle, it's not too dangerous, although it's a bit unnerving. The smaller window is a bit tricky to get to since it's behind my TV set. I only wash the inside of that one, not the outside since it's on the side of the house and it's pretty much a death drop straight down from outside of it.
And then when I was done, I watched my cat walk nonchalantly all over the roof like it was nothing.
