i dont mean to make light of your situation by telling this story (cuz ive been there), but i thought you might get a chuckle out of it...
this happened years ago when i was little...
my grandma also has UC and on the way to lake tahoe with all of us (her grandkids), she had to "go". and when my grandma has to go, get out of the way or you'll get hit! lol
well, the drive to tahoe thru the mountains really has no stop points at all. just a long windy road with a few turns outs.
all of a sudden she veers over to the side of the road, jumps in the back of the minivan we were in, grabs my cousin's barbie box, dumps everything out all over the car, pulls down her pants and craps right in it. all of us scream and jump in the back back seat. smelly!
when she finishes, she grabbed the box, closed it and chucked over the side of the mountain. (yes, i know, we are bad people for littering)
she told us never to mention this again and we went on, while we all laughed in the backseat.
years later, i have UC and i know how she felt.
now my uncles always joke that they are gonna get me a barbie box for my car for christmas!
