She asks for Christmas stories so here's one

Christmas 1980 was different for me and my three children. We had been living with my parentsfor eight years, together with my first husband and then I divorced him for reasons that are irrelevant to this tale. In August 1980 I met Mr M, in October I asked my children what they wanted for Christmas and they said they wanted Mr M to live with us. My father threw a hissy fit and refused to let him through the door so we found an expensive house to rent and the children and I moved out. So we had no money because what we didn't spend on rent we spent on the fuel to get Mr M to work and back.
We asked the children whether they wanted a present or a Christmas dinner because we couldn't afford both. They said they would have a dinner because their father would give them lots of presents.
On Christmas Eve they all went to bed quite late because they had helped to prepare vegetables and make mincepies and do all the things they hadn't been able to do before. Mr M suddenly put on his coat and gave me mine to put on. "Come on" he whispered "this is what my Dad always did"
We went out into the garden very quietly and hid behind a big bush, and from his pocket he produced a string of jingle bells which he shook vigerously. The curtains on the boys' bedroom window shook slightly. Mr M shook the bells again and two little faces appeared.
"I don't care what your name is!" Mr M bellowed "You can't park those reindeer on my roof!"
The curtain dropped, we scurried inside, throwing our coats at the coathooks and kicking off our shoes. We sat ourselves in our chairs as we heard footsteps on the stairs. I carried on with my crocheting and Mr M pretended to be asleep as a little head came around the door.
Nothing was said to us but as they went back upstairs the youngest one asked his brother "How did he do that? How can he be outside shouting and inside asleep?"
If he reads this blog he'll find out won't he?
