Meh, I take a different approach. Always spend time with people so if it is the last time you see them you won't have any regrets.This. I’d have less of a problem if they have an at risk person in the house and asked people to test ahead of time or wear a surgical mask. Vaxx requirement is beyond pointless.
Also, how many more Christmases do they think a 90+ year old is going to have? Statistically speaking they won’t make it to the next one. Personally, I’d want to see my relatives at that age rather than probably miss seeing them for the last time.
I spent years of my life with my grand parents, they would pick me up for lunch at school every day, I would go to their summer house 3 months every year, they would take me to sports events on weekends and when they fly up north I try to see them every week ...
When COVID happened and they said they didn't want to see me if I wasn't vaccinated, I had no problem telling them they wouldn't see me, it was their choice, not mine. Fully aware that my grandfather is 88. I have spent enough time with them already.
I did get a chance to see them when they backed down on their stupid requirement and will see them again in January when I go to Florida.
But I would have no problem if they made up their mind that they don't want to see me, it is their life. I won't risk f*cking up mine.
