My street has permit parking, so it's quite easy to park on--most families have only one car and you can usually park in front of your own house. For some reason though, one of the neighbors has taken a liking to the spot in front of my house, and she never moves her car! It's been parked there for 2 weeks. I saw her getting in it Tuesday morning while I was taking DD2 to baby gym and thought "oooh I'll get to park there when I get back" but she'd come back by then. There was a space in front of her house but I think it's easier to park in front of mine.
So I've parked right behind her and am watching like a hawk to see when she goes (if she ever does) and will nip right in. Am not angry or anything, just sick of looking at her car (2 weeks!) and having to herd DDs across the street everytime we want to drive somewhere.
