I've spent the last few Christmas's on my own. Originally due to circumstances and one son is always working on that day anyway.
I found I enjoyed it. Christmas to me has some unhappy memories anyway, always a lot of pressure, witnessing greed and gluttony, family members leaving me out etc.
When my children were small I'd have to dash all over the place on the day after rushing the dinner, not being able to enjoy a drink or watch my sons enjoy their presents...to keep other people happy. So it wasn't really relaxing at all.
So I have enjoyed the Christmas's I've spent on my own, having a lie in, then in front of the fire and doing what I wanted, watching what I wanted etc. I mostly enjoy my own company anyway. Just as well as I live on my own, no partner.
This year I shall be spending a lot of the day with a friend, but even if I hadn't another Christmas on my own would have been fine by me.
However I will see family on Boxing Day and maybe Christmas Eve so I feel lucky.
If people are lonely without wanting to be I feel for them very much, it must be so hard when family life and fun, parties and gettogethers seem to be everywhere...rubbing salt into the wound. And it hurts probably more this time of year than any other time.
