my mum joked that I"ve probably gone on a list somewhere of potentially derelict parents.
I'd say I'm on there too. I forgot to pick DS1 up from Kindy once and got the phone call .
I forgot to pick up DS1&2 from primary school a couple of years later. My neighbour was picking up her son and walked them home. She got them to wait at her place so she could come and make sure I wasn't in the house collapsed on the floor. Only to find me completely oblivious, and making a fruit salad for when they boys got home. I was just a tad mortified when I realised the time

I was late to pick up DS1 from soccer training a few years later. About 20 minutes late, in winter and it was pouring with rain. He was sitting in one of the coaches cars waiting, the last one there. Way to feel like a crap parent!

You're definitely not alone.

Oh dear, I sound really derelict reading all that
