That sounds good and clear. Allow to meet with one other household only per week, or every ten days, no limit on numbers. Rule of six is easily manipulated, you could meet up with six people from six different households one day, then the next day meet up with a totally different group of six people, so in two days at least 36 different inter actions between different people, (maths not my strong point) . A household is a bubble of sorts, allow one meet up per week between two bubbles. There should be a new dictionary for Covid...furlough, mothball, r rate, curve, asymptomatic, unprecedented, self isolate, shield, test trace, toilet paper, pasta, Cummings effect, Masks . What a year!
