Whatever happened to being appropriate?

I am far from perfect by any means. I was not always as angel as a teenager but my parents did teach me some values. Just a little while ago I was eating a sandwich with out a paper towel under it to catch the crumbs and begin to worry that my mother would catch me. I've been married for 17 years. Dropping crumbs is not a moral issue but it is something as simple as learning morals. 

My father-in-law told me he hated when he had to go stay at a certain aunt's house when he was little because he knew when he came home there would be another baby in the house. He was smart enough to figure this out on his own. It certainly was not told that his mother was with child. No one was going around feeling her belly, asking her about doctor visits and the like. What happened to those days? I was born in 1974. My siblings were never told that my mom was expecting. I was not allowed to say the word pregnant when I was a child...even it was true about someone, I'd get my mouth smacked. My sister told me "virgin" was a bad word and I shouldn't use. Feminine products or any other issues were not up for discussion either. ESPECIALLY around mixed company. If questions came up there was a private talk. Look now, not much later it is advertised everywhere. Ladies don't care to announce personal matters to the whole world. Now we have the internet and other social media where any Tom, Dick, Harry, or Jane can display whatever they want. I do not want to someone ultrasound, that is private. I certainly do not want to see your belly. Cover up your nakedness! Have a little shame! 

Unwed parents used to go around with their heads hanging in shame. Now, people do not know what shame is. Remember the first time you said a bad word in front of an adult. Wow. I was 19 years-old when I said a "little" blackguard word in front of my dad. He assured me I better not do that again if I knew what was good for me. I took his word for it. Like I said, I certainly was no angel but I did have the sense to know what to say and how to act around adults. I never drank. I have tasted some alcoholic beverages. As a matter of fact, I like wine. I have never been drunk. Had of been stupid enough to act that way when I was a teen I would have been trying to hide because I would have been so ashamed and so scared that my parents would find out. Now kids tell everyone they see about how drunk they got and who all they were "with" the night before. We should really be reminding kids how to act because the world is not helping them.
