They feel bad about the mess their child makes (lots of food being dropped, I presume). They should either bring a drop cloth and ask if they can use it or tip really well.
There’s a flaw in this plan. Scrappy Lad wouldn’t feel betrayed. He would be twice as determined to stick by their sides now that they are conveniently together.
RE: “Where on earth do you need a jack-hammer?” – Our house is slab on grade. The floors are concrete, with tile, carpet, or wood directly over the top (with moisture barrier for the wood floor). The water, sewer, and hot water (we have radiant heat) pipes were all put in place before the concrete was poured. The bad news is that nothing can be changed. The good news is that you are extremely unlikely to have a pipe burst when it is encased in concrete, and if there is a clog tools can be run through the pipes to clear them. I have never heard of anyone needing a jackhammer to fix a plumbing issue.
My kiddo gets very cold hands and feet. She recently had a medical procedure done that required her hands and feet to be warmed up to a certain temperature. They got her hands warm with an electric heating pad. Her feet, however, had trouble getting warmed up enough even using a heating pad for half an hour.
If it’s a consistent thing, the gym could install timers that go off when your time on a machine is done (or every X minutes, whichever).
