Well...as long as they're not too much. You need space to keep them, and they're used to living here...

...but, you get lonely when you're up here on your own, don't you? It'd be nice, if you lived closer...people hang out on the roof of the 38-8, or in the rec room downstairs. And even if you don't run into anybody, it's not lonely at all, because there's always somebody home.
