I love the weather, but I don't like the shorter days. I have a tougher time getting up in the morning when it's dark, & I have a tougher time going to the gym at night when it's dark.
Oh, & I live next to an elementary school. I forget over the peace of summer how noisy it is in the mornings. It's only for 15 minutes or so, but listening to 400 loud kids, along w/their 400+ parents, the slamming of 800 car doors & all the accompanying sounds is a little annoying.
ETA: don't worry, I have no intention of slapping any of them.
