I suppose that a contributing factor of funerals is the typical close contact and consoling hugs that would be extremely difficult not to do.
I just watched the funeral of the guy who was my team leader at the time of my retirement. He was 10 months older than me. There were 10 people sitting in family groups at a "social distance". But when a grandson started crying while speaking, naturally Dad went up and cuddled him.
As someone said, "Finally, introverts experience a world that is suited for us. All events cancelled, we don't even have to go through the trouble of flaking out. No one is making random small talk or physical contact. Everybody minding their business", but even we need a cuddle at a funeral.
Content warning. The question I'm about to ask could be rated R and I based on the following comment. It could also generate an emotional rather than rational response in some.
My "research" suggests the above is from before Kenneth Copeland destroyed the virus by blowing on it, but when you see meme's like this doesn't anyone else wonder a bit?
