OMG, there is a special place in hell for that gal.
My father died seven years ago - I'm still not over it. My mother lives in a mother-in-law suite we built at our home for her shortly after his death. She's 84, a handful, drives to Mass every day, and watches Fox News exclusively. She'll call me at the office to scream about democrats, the UN, or anything on the left - they are keeping her young. ;-)
That is so cool. She is really lucky to have you. I'll never forget sitting with one of my older friends as we watched the House Managers getting ringed by some dingbat female demo. All she said was, in a very quiet tone. "Bull sh!t."
