Do I walk away from WAW? (1)

[1foot2]

Came home from work. MIL was watching kids. Picked up the mail and found a notice from the city for an unpaid parking ticket. I was puzzled as I didn't recall getting one. Then I looked at the address of the citation.

Now I know where OM lives.

MIL walks over and looks at me staring at the paper.

"What's that? A parking ticket?"
"Yeah, and I don't remember getting one, so W must have gotten it. What's funny is...the address is on ---- St. (Residential street far from our neighborhood). I'm uh....trying to figure out why she would have been parked there."
MIL pauses. "Oh. Well, at least it's not to expensive." And walks away. No further conversation.

This is so crazy.
