We have friends that either stay with us, or we stay at theirs once a month or so.
Virtually always, they do not appear until after one of us has got up when our DS and their DD (once one of them hears the other they are both awake), gone downstairs, given them breakfast etc.
This weekend was worse than ever - yesterday the children surfaced at nearly 8 (they are both 3), I got up, followed by DH a bit later, and it wasn't for another hour and a half that friends surfaced 'we heard that DD was up and decided to have a lie in'. This morning it was a full hour - and no apology etc.
They never offer to get up with the children in return either.
AIBU to be annoyed by this ?
