What Kirk said... I remember my Dad's generation saying women were "hysterical", but I find throughout my life, they're more "historical" and will drag up an offense from 22 months ago and somehow wedge it into today's argument about something irrelevant.
I echo those wishes for handling your dear aged Mom...I visited my dad daily for over 2 years till he finally gave up and went "home" mid April... it's tiring, but it's the right thing to do.
Good luck with the tyke pulling thru!
If you need excitement, rather than risk matrimonial tranquility, you could try whizzin on high voltage lines, perhaps!
