My roommates' ex-roommate

I was working in my room trying to finish my blog, when suddenly my roommate's ex-roommate came in and asked me if he could use my computer for a short while.

That was like happening totally out of the blue. But then this thing happened a few times before as my roommate, which is actually the owner of this town house, trusted his friends and ex-roommates so much that some of them actually have the key of the house. He also welcomes them to come back and use his place while he's not in Houston, which is like a lot of times. So it's kind of common that someone may show up like this. It would be nice, though, to have some notification in advance.

On the bright side, that sort of woke me up and now I have some energy and incentive to finish some work.
