Driving while texting is extremely dangerous and illegal.
Using your phone while out to dinner is rude in most cases.
Using your phone while waiting for a ride at Disney in my opinion is perfectly sensible. I have a 17 year old son and a soon to be 13 daughter who I have a great relationship with, they have no trepidations to speak to me about any topic. I spend almost all of my free time with my kids. To suggest that because I am playing games on my phone while on a line that I am somehow ignoring or neglecting my kids is very judgmental and wrong. Sorry but I had to get that off my chest.
