What is it with the older generation, that they absolutely hate taking their shoes off in people's houses? My parents are late 70's and never take theirs off, if I suggest it they look uncomfortable and just ignore me. Same with MIL who will occasionally do an awkward check of the soles of her shoes before carrying on through my house wearing them. My 4 year old has been brought up to always remove them in our house or anyone else's, so he'll occasionally ask me why nanny doesn't take hers off, which is difficult to explain, giving that the real reason is that they don't give a sh**
Seriously though, what's with the lack of respect, especially when they can see everyone else doing it.
