Pregnant women can be - inconsistent.
Some women who are with child have a tendency to occasionally change their mind.
By 'a tendency' I mean 'an unstoppable raging urge'. 'Occasionally' is also probably better described as 'all the bloody time'.
Work it to your advantage by making your own preferred suggestions a week in advance. They will be shot down immediately as the fodder of a buffoon, but later presented back to you as almost angelic ideology which must be implemented without further delay.
Pregnant women snore.
They snore with such thunderous force that Sri Lankan fisherman flee inland, Gazelle raise their nostrils to the dusk sky before galloping into the undergrowth, and Californian office workers dive for cover under their desks.
As fear inducing as that may be, there is no scale, Richter or otherwise, that could measure the darkness of the scowl that is unleashed should you indicate your yawning is in any way related to her nocturnal soundtrack.
Nipples take on super powers.
Some days those things can work their magic through woolly cardigans and overcoats. Forget about cutting glass, you could blow a hole in the front door of a Catholic church with one of those things when the time is right.
Unpredictable and dangerous, keep an eye out, or they'll take an eye out.
Pregnant women make life and death decisions.
About your life, at least.
A pregnant woman may take offence to the tired ramblings of a husband who thinks he's funny, but isn't really, and she may decide to slit his throat while he is indulging in his nightly 2 hours of sleep. Then again she may weigh this up against the holiday that that is finally just around the corner and content herself with the knowledge that she will be patting her bump in a Montréal cafe within a week.
Husbands are for life, not just for insemination.
