A little courtesy?

If not that I've made up my mind not to let things get to me easily, I would have schooled a babe yesterday. Funny enough I admire her from afar, her strive to hustle I mean. We used to visit once in a while as kids courtesy of our moms. So we say hi when we run into each other. She thought to advertise something to me and said "Hey, check this and that." My mind was close to thinking insults then I thought "could she be referring to me, naah she isn't" so I ignored.

I find myself greeting almost everyone I run into, even strangers. I often see surprise on the faces of some. They wonder why I would be greeting them when I don't know them or need anything from them. Our society is one in which we're surprised when people do what they ought to do, e.g, politicians. It amuses me, in a bad way, when a kid i'm much older not only doesn't know he should greet me and refuses to respond to my greetings. Do you want me to school your kids for you? We are breeding ill-mannered children. Why then do we complain of the scarcity of gentlemen and ladies? Your jazz must be a "serious something" for you to believe that your spoilt brat would turn out a lady. Your girl doesn't say "good evening, thank you, bless you, sorry, please" and you're happy? Please give yourself a knock on the head and cry for 5 minutes. Then begin to teach her to be who she deserves to be.
The babe that messaged me lacks essential social skills and culture. That I'm not a "Dangote" or being younger than she is doesn't demand respect? You don't show respect because of societal/financial status/age. You show respect because you desire to be respected. Treat people how you want to be treated or stay in your house alone. We should be taught not as adults but as early as possible. Please school your little ones so they can make you happy when you're old and grey. If you're not cultured, please learn.
Thank you.
