I think both adults and kids behave badly everywhere. There are a lot of people out there who only care for number one. People have stopped being polite. Gone are the days of saying "Thank you" and "Please" or "Yes Mame" and "No sir". People don't hold the door open for you anymore. They don't give up their seat to a pregnant women or older person. People are just rude, crude, and selfish.
I've also seen a lot of bias toward children. People make rude and judgemental comments like, "I wish they wouldn't bring kids here" as if anyone with a family should leave their kids at home. Don't like kids? Get used to kids being around because they are everywhere. Sure they can be loud and obnoxious but they are still kids. And they need REAL parents who aren't afraid to disipline them in the right way. I'm not talking about this time out crud, I'm talking about spankings and taking away priveliges. Word of advice: You are not your child's friend. This isn't a popularity contest. Sure they'll probably say they hate you once in awhile but guess what, you are still the parent. They need rules and guidance.
Strollers: Tinkerlor, telling someone "they don't have kids so they couldn't possibly understand" is a pretty lame comment to make. I don't have kids either but I bet I'm 100% more qualified to work with kids than most people. Especially since I work with kids 5 days a week and have training to work with kids. I also have 2 neices, Megan 6 and Rachel 2, that the wife and I have watched on numerous occasions. And YES 8 years old is way too old for any child to be put in a stroller. Let them walk. I'm sure they could use the exercise. If they cry about walking take them to the bathroom and show them that walking may be in their best interest if they know whats good for them.
Cell phones in the park: Actually I AM that important that sometimes I have to have my cell phone with me. For instance, this past vacation I needed to be reached for any questions because of a certain situation at work. Besides cell phones are how me and the wife keep in contact with one another. I don't use them on rides. I don't use them during shows. But I've had to make/receive a call while at the park.
Hmmmmmmm.. did I leave anything out.
