I will NOT panic!!!

About 30 minutes after Mster went down for a nap I heard a knock at the door. 2 construction guys stood there. One of them I recognized as part of the plumbing workers that had to come for the mold incident. Apparently the apartment upstairs that they are building has a tub that doesn't drain properly and the only way to fix it is to cut a hole in my ceiling to get access. I'm not panicking. Really.
