BINGO!!!!!!
To mel373, entitlement is defined as the belief that one is deserving of special priviledges. Because you have a toddler does not entitle you to the luxury of leaving the line and coming back.
Everyone today seems to feel that they have a "special" situation or circumstance that allows them to take advantage of the niceness of those around them. It is great if you say to the one family in line behind you, I'm going to take the kids to the store while DH waits, do you mind? But when you come back, are you going to go and ask the same question to the 20-25 other families that may have joined the line while you were gone.
The problem is that a lot of the kids who were raised to believe that rules are there, but there are exceptions for many different circumstances, are parents now. If my kid has to pee, is thirsty, is hot, is cold, is whiny, the folks around me are not going to suffer. They do not owe me anything. I owe them the decency of not letting my little one make their wait time more miserable. My whole group will leave the line, or the ones that leave the line, will not be coming back. While I appreciate that those around me might be ok with me coming back, I don't feel it is right to expect that priviledge.
We were raised to pee on demand, and not to expect special treatment. When we were on a road trip, and made a pit stop, you went to the bathroom then. If you didn't go then, you were waiting until the entire group needed to stop again....That is, unless it was a border line "classic case of kidney blow." (Dr. Hippert, the Simpsons)
