These posts are evidence of a pandemic fatigue that comes from being told to go back in our cave. Everyone feels it but the stress expresses itself differently in various personalities be it distraction or lashing out. Its a myopic disorder that can and will heal when more degrees of freedom someday return. As you expect some personalities were already damaged before the pandemic and will not change.
All pandemics are different, when you see one pandemic you've seen one pandemic.
I do not know if this fifth wave will be the worst of all or not but accepting change as a good thing does provide new or different opportunities.
we'll meet again, don't know where, don't know when...
