Tonight dh decides to ring his mum. He is quite good about this and keeps in touch every week or 10 days or so.
But tonight is his Mum's yoga night. She has been going to yoga on a Monday night for at least two years. More like three. How come I would remember this before ringing when he can't?
I will not mention the fact that he suggests we have quiche, or pizza, or cheese sandwiches, every time his parents come to stay for a weekend, when his dm cannot eat cheese because it gives her migraines and I have known this about her for the 20+ years we have been married and yet somehow it hasn't made a permanent mark in dh's brain yet
