D said that the dehumidifier helped and she would recommend one for the towers. She also said that when it was humid, they were emptying it once a day. It sounds as if when the heat or a/c were running a lot, it wasn’t such a problem and they didn’t need it.
I think I offered to check on whether a doorstop was needed for the dorm room. The answer is no. The door (Walker Tower) would stay open without a stop.
We plan to sell D’s dorm comforter and sheets. Any suggestions for a safe way to approach that? I’m concerned about the safety of Craigslist.
