That is heart wrenching. That never should have happened and should not continue to happen.
And yet it continues to happen.
Once they get to the other side, all people passing away no doubt understand all truths, including as to why their loving family was not by their sides. But the children are wracked with guilt - maybe forever - because they were not there. They wanted to be there. They could have been there. But they were forbidden out of A FOOLISH FEAR THAT THEY MIGHT CATCH A VIRUS. The fear is foolish because anyone who loves their parent would risk the germs of a hospital (not only covid) to be there to say a last goodbye.
That was taken from them.
