... just in one room, the one where DD crawls around. She's at an age where she picks up the tiniest little thing and puts in in her mouth.
Responses I've had (I always explain the reason why I ask them to):
"oh, my shoes are clean"
"I'd rather not, I'm not wearing socks"
"a bit of dirt won't hurt"
"oh but I'll have to put them on again when I leave"
...then there are the people who conveniently forget and you have to ask them every time they come round...
...and those who take heir shoes off but leave their kids' shoes on.
Am I being unreasonable? Over the top? Should I just forget the rule and let them traipse dog shit into my living room?
