The new roomie-- Yo.
What do I have to say about Yo? He's a friend of RO. He once owned a store near ours, which is how we met him. Yo's store closed. Now he works part time for our store.
After that, I really don't know much about Yo. He appears to be struggling... getting back on his feat after closing his store. That worries me. We've had a succession of roomates who have been struggling to get back on their feet. It always ends bad.
