From elsewhere in The Post: A reader tells the Miss Manners columnist how uncomfortable it is when people bring their babies to social gatherings for 20-year-olds.

“I’m sick of couples looking down their noses at single people like me, with their faux maturity — because that’s what it is, for saying that we don’t want to amend our social habits just so that they can have their baby cake and party while eating it too. When I’m a parent, my kids will be with a sitter, or grandparents, or my hubby and I will be polite enough to stay home. To me, that’s being a mature and responsible parent,” says the letter.
