Sounds like you married a good woman . At least you've got the Indians and Cavs to cheer for.
Except, I am a Reds fan (losing almost as much as the Browns recently) and a Celtics fan. I am originally from Columbus being on the dividing line between Cincinnati and Cleveland so I chose the Reds over the Indians. The Bengals didn't exist at the time, so it was naturally the Browns. And with no pro basketball team in the city I chose the Celtics because John Havlichek was on the team back then and he went to Ohio State.
Oh and yes, in spite of her being a Patriots fanatic, I married a great woman.
