When did...

...everybody start saying SO before they start to talk? I first noticed it a few years ago. Did it flow from software?

...female voices go up in pitch? And get so squeaky? Is it my old ears? I think it started with the "valley girls" years ago but it hasn't gone back down. Is it hormones in the drinking water? Or is it related to fertility?

...people start using "try and" instead of "try to"?

I won't call these pet peeves because I don't think you should have a peeve for a pet.
