It's over the silliest thing as well, it's not even an issue.
My mother was making Yorkshire puddings, and when she took the tray of hot oil out my father commented that the oil wasn't hot enough and it should be smoking. Mum said the tray was really, really hot when it came out and it had been in the oven a long time.
Dad told her to just go ahead, but made a comment about how it wasn't sizzling when she poured the batter in.
He then kept saying how she'd done it wrong, it needed to be hotter, it should be smoking, it should be sizzling, over and over again.
He'd say 'don't worry darling, it's alright, it doesn't matter' in a voice you'd use if someone had just lost their job not messed up Yorkshire puddings ffs.
He'd faux console her, then critique her, then console her again and critique again and again and kept going on about it yet at the same time trying to appear as if he was cheering her up, and being very kind and caring when it was obvious she didn't actually care that much about the bloody Yorkshires anyway and was more upset about the way he was speaking to her.
It just felt really weird from an outside perspective. What was he trying to do? If he really didn't care about the stupid things then why keep going on about it and making her feel bad? The whole thing has left me feeling quite unsettled and uncomfortable about it.
