It shows how clueless she is. I had it and nobody in my house caught it from me(I have three children who were all over me as usual and shared a bed with my husband) then several weeks later my husband had it and again nobody else caught it. We didn’t isolate from each other at all.It’s odd that she says if she is negative then the kids must be negative too. I know a lot of families where one person had Covid and the rest of the household never caught it so even though her and Mark were negative the kids could’ve still passed it round her family members at ham day. I’m not saying she shouldn’t have gone but it’s just a bit pointless testing only the adults
