It's pretty trivial really. I'll try to be quick.
We take our shoes off at home, usually guests do as well, either they just do it or they ask or i might ask nicely.
We have not long ago moved to a new area, I have made new friends, they have been over twice now and both times I didn't ask them to remove shoes and they didn't, i like them I hope we can become good friends but I really would like them to take shoes off next time
So if twice now I have said nothing (both times i somehow missed the moment), how can i say something now without it being awkward! It's too late! Isn't it?
Btw this is not a debate on whether to wear shoes indoors or not to - different homes different rules, i just wish someone would come up with a perfect way of getting people to take their shoes off without any awkwardness! Anyone?
