I refused to go to the PILs house for Christmas while one of DSIL had also gone while day 4 of covid positive, still symptomatic?
(Invited by DPILs who didn't want her to spend Christmas alone and were willing to hedge their bets that they'll be fine as vax-ed. I don't think it's a wise decision but that's their choice).
YABU: It's Christmas, lighten up and live a little.
YANBU: Have they lost the plot? Why would I literally walk into a house where there is current covid.
