I've name changed as details quite specific.
My Granddad is 90. My uncle (DGD's son) lives in another county and hasn't visited since June. Uncle was supposed to be visiting over Christmas but is now in Tier 4. We are in Tier 2.
Uncle has decided he is still going to come. DGD will be fully vaccinated in mid Jan, so we have asked Uncle not to come for Xmas, given it's illegal, and we don't want to put my DGD at any unnecessary risk. Uncle will be travelling into London twice this week before coming to stay.
Uncle has kicked off massively, and now says he isn't going to come on Xmas Day. He is struggling with his mental health so we do feel bad but it's just ONE month until DGD will be vaccinated.
We have now found out Uncle is planning to come up visit DGD in secret on Boxing Day when no-one else is around!
How would you handle this?
