I was born in the 1970s, here are some of my Christmas memories. I remember getting some second hand Lego. It was very different then - model numbers only in three figures, and only basic colours: even green was rare. Also, you had to use your imagination more - doors might not open on houses or cars, so you couldn't actually put a person inside a car.
If someone forgot the batteries for toys, there might be no shops open until after Boxing Day; and if Christmas Day was on Saturday, that meant nothing open until 28th.
I had a toy post office once as well, it had dog licences, and premium bonds among other things. I also had a Ladybird book "The Postal Service" which explained some of these things. Perhaps the book was ahead of its time, as it said "postman or postwoman".
A running joke was when my dad brought the Christmas tree to our house, mum would say "Oh look! A walking Christmas tree", like Mog thought it was, in the book Mog's Christmas. They dropped their needles much more then - I used to enjoy hoovering them. (Hoovers seemed more powerful then - it threatened to devour the sleeves of my jumper, my hair, and the cloth on which the tree stood!)
My aunt and uncle had a creative way of presenting our big presents one year. My brother and I unwrapped a plain scarf each. They grinned at our slightly disappointed faces, then told us that good things come to those who wait. They set a mechanical kitchen timer (which ticked loudly) for three minutes, blindfolded us with our scarves, and told us that we could take them off when the timer rang its bell. That three minutes felt like an eternity! And when we uncovered our eyes, we saw two bikes, decorated with tinsel.
When I was older, here's a funny Christmas memory from the late 80s, when watches which beeped on the hour were fashionable (our headmistress banned them). At midnight mass, we all sat silently waiting for it to begin, waiting and waiting; and in the silence, lots of watches beeped; and for at least another minute, the priest did not appear. He was certainly late for one of the most important events of the year.
