Flak jacket and tin hat on!
As well as leaving my logical brain in the porch (when entering MIL and DIL's home), I put on my imaginary flak jacket and tin hat. I imagine I look like and extra from Dad's Army!
When the unwelcome comments start, I imagine them pinging off my hat. I usually respond with some kind of apology, and quite often plead forgetfulness. "Oh, I'm so sorry, I forgot I shouldn't feed the cat/ wash those pants/ use that saucepan".
Lately, MIL has been agitating about me 'taking' something from her Xmas card making kit. She used to make the most beautiful home-made cards, and I have been trying to encourage her to pursue this hobby. Unfortunately, my efforts have backfired, and she now thinks I have taken something vital from her kit. Sadly, she can't articulate what it is I have taken! If only I knew, I'd go and buy it for her! This morning, she told me I was NOT to go upstairs into her card-making room. So, I have been told! I'm very definitely on the naughty staircase!
When I'm back at my own home (I realise how lucky I am to have a bolt-hole), I use exercise to de-stress. My favourite thing is going for a swim, but I like walking, jogging (at a gentle pace!) and going to the gym. I find exercise of any kind is the best thing for clearing my head. But there are times when it all seems to get too much, and I can't seem to stop cursing myself for whatever mess has occured - even when it is patently not my fault. Those times, I take myself off for a walk, and find something inanimate to abuse so that I can vent my frustration. Kicking an empty plastic milk bottle usually does the trick.
