Don't people have boundaries anymore?

[RebelRogue]

Coworker today(that i barely speak to and only see once a week) asked if she could stay over for a while on my sofa.(think weeks).

Neighbour's kid(5)just knocked on the Door to come and play. Sent her awaty as we're actually having dinner. But why would you just send your kid without checking first?

AIBU to think that SOME people have no boundaries,common sense or basic decency/respect?

For the PP who asked we live in a block of flats (only 3 floors) wouldn't have been that hard for a grownup to shout for me and check first.
What? She's going to shout across the flats to see if her kid can visit? Or is it a turn of phrase I don't know, meaning 'call round and knock on the door'? I'd be a bit by someone's mum shouting at me across the flats...

...and find it more odd/less polite than the kid knocking on the door to ask.
