Well, so far as anyone knows, she never killed any of her old boyfriends, besides Travis. I suppose there's that.
She was kind enough to write Ryan Burns and tell him he was never in any danger from her.
She offered Deanna a freshly baked cookie once.
She might have tipped the Starbucks barristas although there was no testimony to that effect.
She did send Travis's grandma flowers, they could use that, couldn't they?
She smiled when Nurmi said he doesn't like her 9 out of 10 days, that's nice, right?
I thought of a few more possibilities:
She made a mean margarita; albeit she broke a few glasses along the way.
She was a very polite server who always made sure her customers' meals were served promptly.
She's always smiling at the least expected times.
Except for the ex she murdered, she always maintained good relationships with former boyfriends.
She's the perfect role model for younger women in regard to "how not to treat people."
She's thrifty and is an excellent record-keeper (or "not-keeper" as the situation warrants).
