First Bank of Medusa

I have a very strong, and uncommon, sense of loyalty to the banks I do business with. I know this is because I have worked for banks in the past, and have done my banking with my employer, so the sense of "my" bank has been very real. Not everyone feels this way, I understand. But when people talk about how their mortgage has been sold to a different bank several times, I get a strong sense of unease, even though I know it will likely happen to me at some point. But my underlying thought is, why would they sell me? I've been a loyal customer.
