Okay this is for the brave gentlemen reading the thread. Sometimes we are visited by our monthly without warning. If you notice that the print on the CADPAT pants (is that right Vern? I'm a civilian) includes a red blotch, take the initiative and let the woman know. Please. Women are good about this but men try to pretend it isn't there. It's more embarassing for a lady to walk around with that blotch and have 300 people see it, than to have one mature male let her know. Kind of like having your skirt tucked into your pantyhose.
And around house we also have names for the pads and tampons. Pads = Manhole covers, Tampons = Spark Plugs
