1. people who don't keep the lines moving! and i love how in certain ride queues, such as ToT, the castmembers yell "move as close to the doors as you can! there are no lines here, and if someone in front of you is stopped in a nonexistent line, you may move in front of them!" that's not word for word, but close. i LOVE that! because there are still idiots not paying attention and look all shocked and confused when people move in front of them. ha ha!!
2. the GIANT BACKPACKS people wear that stick out five feet behind them
3. people who walk right through the smokers' section and loudly cough and exaggerate not being able to breathe (and no, i don't smoke)
4. "thing 1" and "thing 2" t-shirts (they're not even disney, but i see them worn at disney world more than anywhere else for some reason)
5. people who let their kids pull on and play with the divider rope that holds back the crowd at parades, the rope hitting and snapping back into everyone standing in the front row.6. people who look miserable because their kids are miserable because they try to do too much without breaks.
