Yes. Creating world without any sense of respect for people around you is the thing we really should do. I am talking about parents here, not children. Children are doing their thing as expected of them.
I don’t expect parents to apologize — I have no use for apologies. I expect them to be responsible enough to prevent damage to the people around them. When a child pulls down pants and start to defecate in the aisle of the plane, it IS parent responsibility to make sure that doesn’t happen.
So, stop with apologies and start with responsibility.
