DS had a couple of friends over to play games with today. One - lets call him "J" - has popped round a couple of times before. We're not great buddies with his parents, however know them well enough from the school run, attending parties, school events, etc, etc. On previous occasions, its always been his mum who's dropped him round and collected him. We do the usual small talk on the doorstop for a couple of minutes but nothing more.
Today, however, J's dad came to collect him. Knocked on the door and DS happened to be in the hall so opened it. As I make my way from the lounge, J's dad walks straight in, without any invitation. I meet him at the entrance to the lounge (J's in the hall at this point too) and try to be polite, say "Hi", "it's been a pleasure to have your son round", etc. J's dad offers non-committal noises and instead is more focussed on craning his neck, trying to see inside our lounge, look for all the world like a bloody hotel inspector or something.
DS, J and I make comments about doing this again. J's dad grunts and they go.
I know we all probably like to have a bit of a sneaky gawp at other people's houses. However, AIBU to be taken back a bit by how blatent he was? It just seemed so presumptuous, to stride in and be so nosey. Or am I being a bit precious and this is something many people do?
