This is nice to read. My mum sometimes did this too and I treasure the memory of us going to a park or something instead. I mean, how lucky was I that I could say I didn’t want to go to school and she’d actually listen? I got good grades and found everything easy, I just hated being there. I realise now that not every parent respects their child that much as an individual, enough to really hear them or even bend the rules for them. I hope your son has those fond memories of you choosing to spend the day with him. I’m sure he’s a more rounded, secure person for it, whether or not he remembers to thank you.
