If everyone stuck rigidly to the rules between now and 21st June then there would likely be an infection spike after each milestone because it’s the first time people have been mixing / going out etc
As it is, there’s a lot more people doing their own thing already, especially when the weather is nice
AIBU to think this is actually all part of the plan and is what the government are banking on in order to steadily increase mixing etc rather than big changes on set dates
FWIW I’m boring and compliant so I’m not using this as an excuse to do want I like
