I don't regret going - I learned a lot of things, not all of which I can put into words at the moment.
The only strange note so far was running into Dwight-my-Landlord as we were arriving home, and his solemn insistence he needed to speak with me. Oh hell, I wonder if the rent check didn't clear. At the time I thought it was probably just that I had given notice. Well, I guess I'll find out soon enough.
Update - just checked my account, and the rent check cleared ok. Hmmm...
