What do you call a woman who's feeling "emotional"?

Solution 1:

Hormonal

You seem a little hormonal this week, why don't you pour a glass of red and run a bath.

You convey that your partner is 'acting up' but acknowledging it is neither persons fault - biology is biology after all and can't be helped.

Solution 2:

Bearing in mind your specific request for non-vulgar terms, and being concerned with my own health and safety, the most commonly used words I use to address my better half when she is in such a state would be

honey
dearest
baby
princess
sweetheart
buttercup
pumpkin
cupcake
darling

This is one of the rules to be found in the Handbook for the Married Man, the invaluable standard work that is traditionally only handed to men after they get married. It is the same work that advises against honest answers to questions that start with does this ..., and explains the possible meanings of nothing in response to “what's the matter?”. The latter is a chapter that many of us men never get to fully comprehend, though.
