What will you do?
We usually have the four of us (two young adult sons) my parents and my sister and her family (two teens). TBH as the children have got older it's been hard enough to make the day special/different to any other day but if it's just the four of us I can't see it being much different to today.
What do you have planned?
Will you comply with the no mixing of households. It's already in play here, although my sister is in another area where it's not. My parents are being very compliant, although my FB feed suggests most of people aren't.
