Crime is up, violence (murder, Domestic Violence, Disorderly Conduct, armed robbery, carjacking), drug overdoses, extreme drunkenness and suicide have increased since this started and I constantly see people whining about not being able to see friends & family. The protests and riots are, IMO, directly connected to these feelings and personally, I think a lot of people need to start to think, rather than only feeling, when they make decisions. People who are prone to becoming extremely affected in some way (could be as simple as being brought to tears at the slightest hint of sadness all the way to explosive outbursts or violence) have issues that should be treated. People who were very sensitive before need to develop a 'thicker skin'. I can't imagine what would have happened at the start of WWII if people were as sensitive as they are now- I doubt the war would have gone the way it did.
I'm not saying that people should stop caring but I think they need to look at things differently- dealing with stress requires different thinking and one thing I have seen as a recommendation is "If you can't change it, don't worry about it to the point of losing control". Over-reacting to small, insignificant events is a major cause of violence and it can be something so simple as when someone gives a mean look at someone- this is sometimes called 'mean-mugging' and people have killed when it happened. That's just stupid. Another reason given is "He disrespected me". Boo hoo- I think people should give basic respect to someone they encounter for the first time, just as a measure of civility but beyond that, don't expect more. Respect is earned or lost, it should be assumed that someone receives a huge pile of it just because they exist but people really should think about this- the first time meeting someone, be a decent person. Be cordial, friendly, nice; whatever someone wants to call it. No need to bow and scrape, but be nice. Greet them in some way- say "Hi", "How's it going?", etc. Acknowledge them, don't just look away and make them think you're ignoring them, especially if you don't know them.
I don't want to be a court jester, but I like to make people laugh and it's better than the mood they may have been in at the time. It takes the edge off and I can't think of many people who don't need that right now.
