I realize, perhaps better than anyone, that it’s not polite to ask others about their reproductive plans. I’ve long ranted about how much it annoyed me when friends, family members and even perfect strangers would inquire about a possible plunge into parenthood. Even now, as most of my readers know, I get aggravated when people ask whether my 2-year-old daughter, Reese, will ever be a sister.Not only are these questions, more often than not, inappropriate, they actually can carry with them an emotional punch.
