I've never had a 'worst' christmas present... being a JW all my life (until recently) they have been few and far between. But I've always treasured memories of the ones I've had, so for me it's the 'best'. As a child of about 6, a neighbour came round and gave me a 'stocking' full of chocolate bars and sweets and some warm fluffy mittens, over 60 years later I have never forgotten it. At school, age 12, my best school friend, knowing I didn't celebrate it and reciprocate her gift bought me a necklace and some perfume. I treasured it for years.
I know my parents tried to make up for the lack of christmas presents by buying us gifts when they could and they were always treasured and I did the same for my own children, but those christmas gifts as a child felt quite special to me.
