Let's Talk Movie Etiquette, People

I went to see a movie this evening, on a weeknight when the theater had maybe 15 other people in it. And yet the following still happened in that small crowd:
1) A toddler was allowed to wander around the seats (though to the parents' credit, they took the kid outside when he started yelling). This was not exactly a family movie.
2) THREE people in front of me were texting with that annoying cellphone glow as a distraction.
3) Another person actually answered their cell and whispered through a short conversation (it did not sound like an emergency to me) during a relatively quiet, emotional scene.
4) There were the loud guffawer/commentators sitting off to my right.

What are the odds of all that happening in a small audience? Or maybe the offenders felt more at liberty to forget all movie-going etiquette because there were less people? I just don't know. It seems like common sense and respect to not text, talk loudly, let a toddler roam around or answer a cellphone during a film. I especially curse the day that texting became popular.

All I have to say is urgh.
