Move from Self Isolation to a bubble of other households

Essentially rather than using a specific number of people (i.e. 10) for the proposed "meeting up with a small defined group", instead set the restriction to apply to a set number of households. such as two or three.

The idea is each household (regardless of size) allows themselves to set a small bubble around them that contains other households they can interact with. The households should be in the same immediate area as yours. If you live in Edinburgh, the households that you interact with should likewise be in or around Edinburgh.

For example a household of three people (2 Adults + 1 Child) setup their bubble is setup to interact with three other households:

- A Parents household containing 2 people (2 Adults)
- Their Siblings household containing 4 people (2 Adults + 2 Children)
- A friends household containing 3 people (2 Adults + 1 Child)

Adding all together that is a bubble of 12 people surrounding the household, with 15 people interacting with one another regularly. The above is an example for families with children that naturally would tend to interact with similar households. For households that only contain a single person or couple, interacting with a similar households would breed a smaller bubble.

The advantage I believe with with limiting to households:

- If there is signs of Covid-19 within one of the households in your bubble, you can both easily sever contact with one and other, and isolate the entire household.
- By using households it will naturally limit the overall number of people you come into contact with and puts a defined figure on your bubble size
- It would give people & families freedom to choose and setup a bubble that suits their household circumstances, over that of individual.
- Households could share responsibilities with, and help care for one and other (childcare, shopping, etc.)
- People can achieve safe physical contact with close family and friends.

Whether we are a family with children, someone who lives on their own, or a couple living together, socially we cannot continue to keep ourselves completely locked away from everyone. People living on their own need a mental health boost. It's important children interact with other children and not just their parents. Couples sometimes just a break from one another.

I believe this idea works better than limiting to a specific number of people as it takes into account people surrounding others that I would want to interact with. I could easily come up with a list of 10 friends I personally could and would want to have in my bubble, But that may not take into account each of my friend's partners, children, and other household members that I in turn will be exposing myself to.
