Quick question about the 'rules'.

Not breaking any rules with one friend as I can see. As long as you go in separate cars. Most of the garden centres are outdoors and ours have set up cash points in little shed type huts

Neither of us lives alone.

Also, if either of you live alone, could it not come under the support bubble category?

I think it’s fine now actually as long as you count it as exercise! The only change from Momday is that you can sit down on a bench and have a cup of coffee. I say go for it!
