Ask your bubby what the title means. I will give an example:
I just read the local neighborhood bulletin. A lady writes that her little son has ADD and NEEDS to get out. So she sends him out to the supermarket to buy food. But they have a policy not to let children in. PLEASE HELP, she cries. Why can't my son go to the supermarket???
LAAAADDDYYYYY!!!! I will tell you why. Because there is a highly contagious disease going around the world that has already taken the lives of 45,541 46,062 people [and 912,650 917,913 diagnosed as sick w/ the virus - those changes were in the last few MINUTES] with many more victims to come רח"ל [Trump is suggesting 100,000 to 250,000 רח"ל רח"ל רח"ל]. You are irresponsible sending your son to roam the neighborhood because he needs to get out. Lives are at stake. He touches something that was touched by an infected person and he will likely get sick [most of the deaths aren't children]. As a carrier - he can infect other people and KILL THEM. It is hard having him home all day and he is probably climbing the walls but better that than a much worse alternative.
It is a very deep lesson in human nature to observe how otherwise intelligent people can lose all rational faculties. We have seen it in the last month COUNTLESS TIMES!
I hope and pray that we use the wisdom and understanding with which Hashem endowed us to act wisely and guard ourselves from all harm!!
