...after already having had it stolen once, yes, that's mainly it. Parking your bike by dropping it on the sidewalk is another, minor irritation. I wonder if he paid for that bike himself....

As for leaving it in the path, I'm pretty nasty about that sometimes...I usually notice that problem when the kids are already inside, and rather than figure out whose bike it is and making them move it, I will move it myself......out of sight around the corner of the building to give them a scare.
