Margs, I object to the 'enforced jollity' rule too. Sorry, I do!
I have to go to my daughter's place (no choice really) slap on a smile and look happy, play with the grandkids, eat a lot (despite being in pain) and wait for the kindly lift home - a welcome escape from noisy kids and far too much food!
Thank Heavens, I have a little dog who can't be left for long. Therefore, a long day or overnight stay are completely out of the question. Isn't that great? The only time we took her out in my daughter's car, she threw up into that socket where the gear stick sits - such a clever girl!
