My mum is coming to my house and she's always invasive about arrival time.
I asked her yesterday and she said she didn't know. Today I messaged her (around 1.45pm) asking if she had left yet. She said "not long left" but it turns out she's 1/3 of the way through the journey (they are retired and stop alot for drinks/toilet/food). It's a 2.15 min journey without stops.
Aibu for thinking it's a bit rude to not say "leaving now" when you've left or give some sort of indication on yh time. Eg "will prob be there around 6pm".
There is a back story, won't divulge too much as it's really outing.
