Seeing my family is the key one. Would normally spend Boxing Day with my parents, sister, bil, little nephew, brother and his partner. This year - none of them as too far for a day trip.
Today should be my Nana's 93rd birthday. She died this summer. We would normally have been visiting her today to drop gifts off. It's a huge family and they'd be lots of us dropping in and out throughout the day.
Tomorrow I'd normally be visiting my other nana and grandad to drop gifts off, but my nana died in May (and grandad died last summer) so not doing that either.
We will have MIL for the duration, from tonight til about the 27th I think. My FIL died in April so it's her first Christmas without him. But we make it a good and a happy one regardless.
After family, then seeing friends:
Dinner out with friends on Christmas Day - we all normally go out for a curry, having dropped having a traditional lunch a few years back.
Dropping gifts off with other friends, maybe having the odd Christmas topple with them.
People are who I'm missing. The rest I'm not so bothered about.
