I learned that running the surgeons office.
My H did take pity on some redneck lady this fall that had bees inbetween the first and second floor of her house with honey dripping through the ceiling, and allowed her to pay late, and she of course attempted to dupe us. His degree is finance, and he worked for high risk loan place when he got out of school so he was all over it, and she magically had the funds for us when he presented with some sort of scary file for lein on property or something. LOL.
I let him handle it.
