Hate:
Wallpaper removal. I've removed all of the paper and the backing. Unfortunately, the glue decided to stick around. Now I get to go over it again and take the glue off, before doing drywall repair to many many places, and then paint the walls. I think that I want to kill all of the people that lived in this house before I did.
Water main repair. I don't know if it can actually be called repair, since I had to replace the whole thing. Built in 1979, the geniuses that built up my area decided that PVC hose would make a sufficient water main. I'm just surprised that mine lasted 26 years (I learned later that most in my neighborhood had begun to leak years before I moved there) before flooding my front yard and producing a $300 water bill.
Love:
Anything that involves a hammmer, pry bar, drill, or circle saw.
