Human Etiquette

I don't know about you, but I was raised to be polite. Being courteous was just second nature to me, not something I had to work at. Along with acting on that I also expected it from others-just common courtesy I suppose. So is it unusual that I am taken aback when dealing with the people of today who not only are rude but also look at you like you have three heads when you are respectful and/or nice to them? I find that anytime I'm out, people who are not "conscious" of their poor behavior overwhelm me with their absolute callousness in response to my politeness. Yes, I did just hold that door open for you- you are welcome. I'm sorry but yes I did just smile,nod and say hello to you. Even more then that though is the complaining I hear from the above mentioned people saying others are not kind to them. If you are to shoot down any of my genuinely nice actions toward you, then why are you complaining? I know that if we were to step into a time machine we would learn so much from our ancestors in the lessons of proper etiquette of human relations. What do we gain if we allow all strangers to remain so? If we could start connecting with those we are not in close relationship to I feel that this world would be much more peaceful.
When meeting a new person do we always have to jump to conclusions that they're going to mislead us in some way? I think that it's our attitudes that cause people to mislead us in the end. I believe if you expect those types of things to happen to you, you have basically "willed" it to happen. How then can we complain? "Do unto others as you'd have them do unto you" speaks volumes. It's so simple. So true. Yet, it is no longer taken seriously and we have become so lazy with our relationships that they are passing before our eyes and we don't even realize it. If we could put the energy that we pour into doubting each other into accepting and loving one another-how wonderful would this life be?! As I write this I am learning, I am taking in these words and finding that they apply to me as much as to those I hope to touch. We constantly are trying to find the differences in us and our peers when we should be bonding over our likenesses. Again, with this I find the word "lazy" to describe what we as humans have become. It's just too much effort to care anymore. I feel that the effort used to piece back together the relationships we ruined with our neglect in the first place is far more exerted then if we just had cared in the first place. Does that make any sense?
