..... for asking someone NOT to visit?

ExD, IMO you are being totally sensible. (DH & I continue to see friends in gardens only, and keeping at an appropriate distance.) If your family can't understand the situation, then that's their problem, not yours.

Not only is it against the law we have to keep to our ‘bubbles’-otherwise this virus will take hold again. You are totally in the right to refuse visitors they shouldn’t be asking anyway !

No, you are perfectly within your rights to say 'no' to them. It is your health and safety that comes first and they should respect that.

You did right ExD.

I agree with everyone else, take whatever precautions you feel are necessary ExD. It's a bit of a cheek to invite yourself to someone's house at present.

It's quite OK, under present circumstances, to remind people that you can't have visitors - especially as you're over 80. Of course, you can't be expected to sit outdoors in the cold either!

Of course you are not being unreasonable. They are if they don't like you turning them down.

No - you haven’t been unreasonable - they are being unreasonable asking to visit. You were right to say no.

I worry about all the people who seem to be behaving as if all restrictions have been lifted. Officially nothing has been announced and nowhere does it suggest that indoor visits are allowed.

yes, they were at fault, not you.
they should have asked if you are having/ would like visitors.
don't worry about it.
safety comes first.
if you H is not being so careful, all the more reason for you to be extra vigilant, for your own preservation as well as his.
and i bet you cook, clean,launder etc for him.
just casually mention that you don't want to get ill as he might not be up to speed with all those skills.
as well as nursing you.
that might make him think.

you haven't been unreasonable you shouldn't be having visitors indoors yet and I'd not want to be sitting outside in the evening if I was you either

I agree with Calendergirl, & your relatives should respect & understand your decision. Best wishes

No, I don’t think you are. Your visitors should have asked you if you are having people round yet, and should respect your views.
Personally, I wouldn’t dream of inviting myself round to anyone else at the moment, and don’t expect them to come to me either.
