Everyone seems to have a guess

Much like a woman's age or weight, it's probably a bad call to venture a guess as to how pregnant she is.  If you do feel compelled, just like age and weight guess low.  (And if you do guess wrong, don't compound your mistake by then making an incredulous face when she says she's got 2 more months to go than you thought she did).  I'm not sure I'd have thought about it much before, but it seems to happen to Claire a lot.
