Nothing at all. I haven't seen anyone to ask. I saw the grandmother in the yard once but she speaks Creole so I couldn't talk to her, anyway. Even if I could, I would be uncomfortable bringing such a thing up if it was not brought up to me.
Heck, I think they might be moving out in a hurry! I saw a lot of boxes being loaded on a pick up truck and someone mowed the lawn! That never happens!!! ;-) So maybe the landlord is getting it ready to rent out, again.
