OK - I think there is now an app for just about everything. Have you heard about the Menstrual Calendar App for men?
It's a calendar that tracks the Menstrual Cycle of your wife (or girlfriend). They say it helps you keep track and be 'on guard' during those times when she... well... might be having less than a good day.
The concept goes further into simultaneously tracking the cycles of your daughter, mom, sister, secretary, etc. What do you think of that? Too over the top?
I don't know. I am blessed to have a spouse that is not overtly affected by the 'curse.' However, it seems that, if done with the right motives, this might be an effective way for a guy to give a gal in his life the 'benefit of the doubt' during her less sensitive moments during the month.
Certainly an interesting concept.
