Lynda, I figured they must have something, of course as a ex-teacher you know more than anyone, that you can't learn IF you ALREADY think you know it all.
A_A,
We need MORE crusty old SOB's telling like it is, I don't know the "AGE" requirement for the position, but I'm thinking it's as much about the right attitude as the years

Of course being a grey bearded crusty SOB, gives you the "proper" look! Clint Eastwood in the UNFORGIVEN has it down pat!
The local park I exercise in has a 6 ft dog leash law on the trails, and provides bags for cleaning up the poo. Almost every time I'm out there, I end up "educating/infuriating" someone who thinks the rules apply for the OTHER guy.
I used to walk by, but now I say something. The people that take it well, either were honestly unaware, or know their in the wrong, and embarrassed that someone confronted them.
Then there are the one's, young/old who not only KNOW their doing wrong, they don't care and will argue and verbally threaten me for asking them to obey the rules.
I have a big puncture scar on my right forearm, front and back, from my UPS driver days. A Ladies Great Dane that she didn't have control over, clamped on me, and caused serious nerve damage, which to this day, still bothers me. Of COURSE she told me her dog had never bit anyone, and I must of done something wrong

When the leash-less dog owners start up about THEIR dog being harmless/won't bite anyone, I show them my scar!!
That and my telling them I'll turn them in a ranger station and they'll lose park privileges, works with 99% of them.
The other 1 % just walk off in a huff, and I turn them in. The park employees/rangers all know me, and since their shorthanded do too budget shortfalls, don't have a problem with me saying something.
I find the older I get, the less apt I'm too tolerate bad behavior, especially when people consciously flaunt the rules. I guess you get too a point in your life, where you just can't take it anymore

Must be those CRUSTY SOB years
