My mother in law is consistently just a huge pain in the butt. The worst time of the year for myself and others is when she simply just decides to spend a very long weekend in my home. My mother in law sets up her own camp and in 1 bathroom and complains all weekend long to me. The complaints are usually about the water pressure in her very private shower, my cooking or the temperature control in the kitchen, last year the big complaint was about the level of heating I and supplied. Apparently my central heating idea was not nearly nice enough for her at all. She was very cold the entire night, whole afternoon and weekend. So what I did last year was get a space furnace for her room. I had the space oil furnace cranked up very high and never turned it off in there. Still, that did not appease her very well. Also she had simply complained about the little space oil furnace taking up the entire floor space that her stuff could go. So this year I am very prepared. I installed a ductless mini split in the spare kitchen. The mini break has its very own thermostat so my mother in law can simply just change the temperature until she is pleased. Also the mini split system is simply equipped with both heating and cooling. So she can even use the AC system if she wants. It does smell that I believe she will even just alter the temperature control program to where I am paying a very huge fortune. But, truthfully I would really just about pay anything not to hear her complain for the entire weekend that he actually stays over. Any amount of heating is worth it to me for sure. Maybe this year she will be happy for once.
