Sure. But while there is no end in sight, despair will rule. Whether it's reasonable to want a fixed timetable or not.
This is also why I mentioned criteria - even if not a fixed timetable, we could at least know what sort of criteria would trigger a rule change. I.E. when we get down to X cases per day, X deaths etc etc, the schools will open. If it keeps falling then the rule of six reapplies in outdoor public spaces ...
At least something rather than just being locked down indefinitely.
I agree the lifting of Lockdown 2 was a really poor choice.
