There’s more to this, but to keep it brief:
Someone messaged me today and asked if they should pop over for a coffee and catch up. I said yes, that I had one or two things to do, and suggested a time two hours from when we were messaging. They sent a vague reply.
It’s now well over an hour from that suggested time and they haven’t appeared.
AIBU: chill out, your time was a suggestion and they don’t have to stick to that
YANBU: they should have said if that was too early
