Why can't people #$?!@!?

I have questions. Maybe one of you has the answers. Or some of them. (Note: Many of these questions are rhetorical. That is, I'm not really expecting an answer.)

Why can't people (other than doctors) turn their mobile devices off (or at least put them on mute) in theaters? Can whatever it is really not wait?

Why do people bring young children to fancy restaurants after 6:30 -- or to R-rated movies?

Why do brunettes who bleach their hair blond wait until they have two (or more) inches of brown roots showing to dye their hair again? And why do so many bottle blonds insist they are naturally blond, or were when they were young?

What is the deal with tattoos? Is there something in the ink that makes tattooing highly addictive? Do people understand that tattoos are permanent (or very difficult/expensive to remove) -- and look ridiculous when you are over 50 (or 40)?

Why do people sign up for classes (or gym memberships), when they know they aren't going to attend -- or schedule appointments at the time of their class?

Why is it so frikkin' hard for people to be on time, especially in this age of electronic reminders? And why do people wait until they are late to notify you?

And speaking of waiting.... Why do people wait until they are actually turning (as opposed to before they make a turn) to use their turn signal? And why do so many people think they don't need to use turn signals? Do you really think other drivers are psychic? (Psychotic, yes; psychic, no.)

Why do people say "Let's do lunch!" when they have no interest in or time to "do lunch"?

Similarly, why do people inform you they will be visiting your town or city -- and then tell you they have no time or interest in seeing you?

Why do people leave the Subject line in email blank? Are we supposed to guess what the email is about?

Why do people send spam email? Do you really think someone is going to wire money to a bank in Nigeria, or buy your penis enlargement pills, or have you find them a slut? (On second thought....)

Why do people forgive the sinner but never praise the saint?

Why is it so friggin' hard to pass strict gun control measures in this country? (This would be an example of a rhetorical question.) Even the NRA was for it... before it was against it. (You want to dramatically reduce the number of gun-related deaths in this country? Dramatically reduce the number of guns.)

Why are so many people afraid of and/or against a single-payer insurance system, like the UK and Canada have? Do people really love their health insurance companies and overspending on health care so much? (Again, this is a rhetorical question. Though feel free to dazzle me with your brilliance.)

I have more questions. But I think that's enough for now.
