Growing Together: never had a long-lost relative ask to stay over?

So far the only sleepover I've had was when Justin Delgato came to my sim's house for a few days. I was a little leery, I did not know what to expect. He came over on Monday and left on Friday, and I think he and his wife were having issues, he was always sad. For my sim it was no big deal, he continued with his thing as if he wasn't there. Justin cleaned the house every day, so it was a win-win situation. :D
