If you are the gran I saw today then hello. 
Was in playpark with my DC. Stood around daydreaming and a woman - guessing around mid-50s age - called me over, said there was room to sit on the same bench as her.
Moment later 3 DC ran up to her calling her gran and asking her to help them up on a climbing frame. They were around 7 years old, and seemed healthy happy kids.
She told them no way, she wasn't going to help them, she couldn't touch them at all, and jokingly admonished them for asking. They moaned then ran off to play again.
I was agog. But didn't day anything. But she struck up a chat with me and said she minds them half the week when her adult DD works. Said she hasn't touched, hugged or been near them since March (start of lockdown). Said she'd never forgive herself if she made them sick or harmed them.
I didn't wap nt to get into a big debate about Covid in the playpark, but am I mad for thinking that she is OTT and messing up their minds and relationship?
Disclaimer: I have minimal family support and no unpaid childcare for my DC, so I'm not sure if that is colouring my view.
What are you all doing?
