I think that quite a few mums have left the baby outside a shop. I did too. Luckily only a few minutes from home, and no harm done.
As for Christmas, I can't work up much enthusiasm for it, these days. I don't have many gifts to buy. Half the family lives in Australia and parcel post costs a fortune. We don't bother with adult gifts, and I send some cash to buy gifts for the two GC. They get what they want that way.
DD and 2 adult GC, and DS, who all live near me get a token gift and some cash, which is how they like it.
Since DH died I usually go to DD for Christmas dinner. Last year, to celebrate our freedom to meet again, she invited a group of friends too. I knew that they would party until late, so planned to make an early exit. In the event someone had brought their elderly father, and the pair of us ended up sitting in the quietest room we could find. He had forgotten his hearing aid, and I felt too mean to leave him there alone, so it was after midnight before I escaped. I'm not fond of parties, and prefer a quiet Christmas, so I will plan more time at home this year. I would love to love Christmas, and all the hoo-ha about it, but I much prefer a peaceful day at home.
