Once a month

This is too funny and I don't want to forget it. But, I think it may be TMI for facebook.  M was having a stomach ache.  She sometimes gets these when she has to go to the bathroom.  I was asking her if she was ok and she said yes, it't the same stomach ache she gets, you know, about once a month.  The way she said it, and yes we were in a public place, was hilarious.  If she only knew about the stomach aches (cramps) she will start to get once a month in a few years.
