I do often think that the reason I (and many moms) are more emotional (read: cry at commercials, well up with pride at a tball hit) is because our emotions are so close to the surface (or the 'brink', I suppose). So raw, just asking, waiting to be tapped.
(I can't, however, get behind the 'take a month away' method...)
