I prefer to have Stampy carrying Bart than having him locked in the house, but Bart is busy being a nutcracker right now, so Stampy is spending his time inside.
Actually, right now, most characters are inside. It's mostly so I can more easily spot feds, and partly because it's snowy out and most characters don't have a coat on.
I also prioritized buying Apu's apartment building when it came out, so he had a place to live. I felt bad about all the time he spent at the Kwik e mart. (I've worked at a convenience store.)
