I know IABU but at this time of year it really sucks. He’s ducked out of visiting any of my siblings and I know on Xmas day (I’m hosting my parents) he’ll skulk off upstairs for most of it and make minimal conversation at the table.
I get that all the socialising at this time of year is tough for introverts but I’m fed up of being the lone adult representative for our family unit at all things festive. It sucks. Tbh it does my nut in most of the year round but it’s brought into sharp focus at Xmas.
