I was 13 when my Mum died & I had 3 younger brothers and sisters. Mum died in August and the first Christmas after that loomed like the worst nighmare. My 2 year old sister had been very ill with measles, and against medical advice, Dad wouldn't let her be admitted to hospital because he was terrified that she wouldn't come back home. Like Mum. So in early December he gave up work to look after her at home.
This was in the days before benefits. If you didn't have a job you had no money. Two weeks before Christmas, when the 3 younger ones were in bed, Dad told me that he couldn't afford presents for all of us, so as I was the oldest I'd have to accept that the younger children would get presents, but I wouldn't. It's difficult to describe how that all felt, but I remember it with chrystal clarity. God only knows how my father felt.
That same evening, there was a knock at the door, Dad answered and I could hear murmuring in the hallway. He eventually came back in carrying a brown paper carrier bag with string handles half full of loose coins collected by his work colleagues. With tears streaming down his face he said " Girl. Don't ever let anyone tell you that there is no such thing as Father Christmas".
So to answer the OP.....yes, of course Father Christmas is real
