Point of consumer-relations etiquette: Unless you are absolutely certain the customer with whom you are conversing is expecting a child, under no circumstances should you ask her when she's due.
Harrumph. Not going there for coffee again anytime soon.
I've spent the whole day asking people at work if I look pregnant. Consensus is that my sweater is rather baggy, the sort of thing a newly pregnant woman might wear. It's also the sort of thing a plump woman might wear if she were not inclined to dress herself in low-cut jeans and high-cut shirts--the sort that make the wearer look like a tube of Pillsbury's biscuit dough that just exploded.
Ah, well. Better to be called pregnant than fat. I guess. Though you'd think the fact that I was buying coffee would be a hint, wouldn't you? Most pregnant women I've ever come across cut out caffeine right away.
