Thank you both. Actually I do only buy for my adult children and my best friend now, so the actual task of shopping isn't that bad. My Christmases have almost always been quiet: as a child it was only ever me, mum and dad, and since I left home to get married I've spent one Christmas with my in-laws, and two or three with my parents before my dad became too ill to travel, then he died and it was just mum, and now she's gone. Otherwise it's only been me and my husband and the children.
I don't particularly want to be with my in-laws, but they have never wanted to come and stay with us ( and now FIL can't travel anyway) and have only invited us once in all the years that we have been married, and that was before the children were born.
I have a deep, deep longing for a large family, even if it can be stressful, which I know full well how much it can be just from reading peoples' stories on here. I feel for my kids too, as their Christmases are pretty boring for them! My son did go to the pub with his friend once, which pleased me. My Mother in law would have been aghast at his abandoning "the family" like that!
