Ok here's another one

You are bubbled with a single person so you and this single person are one household. This single person has a university child return for the christmas week. Therefore university child joins that single person household. However, single person is no longer single person! So they can't bubble with you anymore can they? Or at least they must now count as household 2?

Are you also single? If you are, yes you can bubble with them.
If you aren’t, you can’t be in a bubble with them until the student goes back to uni, or if you’re part of their Christmas bubble during 23-27.

Or at least that is how I understand it.

A bubble is one household of any size plus one single person household. Are both original households single person?

Would be reasonable to unbubble for duration of the Uni student's return home. Morally I don't think it matters what you do.

Nope we're not single! So I was right. Better start explaining and wish me luck haha.

But that'll be two total households if we bubble with them, no longer 1. So we can only see one other household and that other household can't see anyone else.

If you're the other half of the bubble and you aren't a single adult household, then no, you can't be a bubble once the student returns home (assuming the student is 18 or over).

Surely they should understand that. It's not that complicated. They have two adults living there, they're no longer a single adult household 🤷🏻‍♀️
