Me and my cousin (we are close) have just lost our Grandma. Obviously everyone's very sad. My cousin text me on Wednesday asking how I was doing and I said "Ive been better to be honest, just feels like there's a lot going on and I'm feeling overwhelmed."
She took over 2 days to reply.
If it was me and I got that from a close relative, I'd have replied that day or at minimum day after.
AIBU? understand everyone's busy but its a really difficult time for us all. She is single, works part time and has no kids (im not saying people without kids can't be busy, just for context, shes not so rushed off her feet running around after loads of kids).
