You will never stop ignorant people from being that way. How about the slow drivers in passing lane that wont move over, im finding it better to try and ignore them instead of getting blood pressure up, Saw two kids playing games on their phone in Red Lobster waiting area they were sitting with there parents,an elderly lady with a cane came in, then stood next to them she needed a seat,parents never made there kids get up. I was standing at other end of the room. Seems to be all about me day and age. Makes me appreciate the mannerly ,considerate nice people that are still out there.
