We have had events for years despite the fact they spread the flu and many people die of that. Once less people are dying of covid than the flu it would be unreasonable not to return to normal. That is not the case yet, but we are fairly rapidly moving that way.
Funny you say that, as I was thinking the same, but differently. I don't think we will ever be allowed to go to work with a flu and Paracetamol, like it was acceptable before... now that we know that spreading viruses actually kill people.
I honestly didn't know that almost 10,000 people die of flu every year, despite vaccines and all... if you asked me last year, I would have thought maybe a few hundred frail elderly, nowhere near 10K.
Now that we are all very aware of what respiratory viruses do, we are not going back to that way of living, it just won't be socially acceptable
