Yes, I have 'mother' friends like that too. Though most of the time the 'mother' comments are on daily decision type items. Stuff my own mother never told me.
Like 'bring a coat' or 'aren't your hands cold? you should put on your gloves' or 'don't bring a big bottle of booze to the weekend at the cottage - that's way too much alcohol!'
Jeesh. I realize my mom was a bit different not telling me to put on my coat when I went out to play but she figured I was smart enough to come in and get it if I got cold. Obviously this was not when I was a baby or when it was arctic type weather but by the time I was out playing with the kids I was old enough to know what I should be wearing.
I have friends who are *constantly* telling their kids to drink some water or go to the bathroom or put on a coat. Sure fine when they are little but now some of those kids are double digits in age! Surely they must know when they have to go to the bathroom by then! They aren't stupid but having mom constantly tell them means they likely don't listen to their own body.
So because they are constantly telling their kids stuff they probably don't know how to shut that off when they see a 'mothering' situation.
