Lady gets her Christmas lights stolen so she fires back with a sign full of Christmas spirit. (By the way, I had that exact same message on my Christmas cards last year. Huge crowd pleaser.)
But I'm kind of confused about the "stereotype" line. I didn't see any mention of race or ethnicity in the story so I guess she means that it's true that thieves possesses the stereotype of a thief. Can't argue with that logic. I'm guessing she's an FBI profiler during the day.
Now if they'll own revise the Charlie Brown Christmas Special to have Linus read that sign at the end. There wouldn't be a dry eye in the country. Peace on Earth. Good will towards men.
