Give a greeting, just say hello. Do not question what they do and why, it doesn't matter to God and it should not matter to you. You go along in life and you wonder, 'Does anyone really care?' Will they miss you when you're gone? Is there a point to it all? If you have the ability to look at the big picture you may even wonder more than you do today?
We go out and we see, we see things that we do not agree with. We see that many others do not think the same way as you do. Do they not realize that the world does not revolve around them and life as we know it would go on without them?
How do I know, how do you know what is really real and which way we should turn? Stop being a pompous rear-end, wake up and smell the coffee! You are not the first person to give birth, your child is not the first one ever born. This does not mean they are not important to you and your immediate family but please let go of your over inflated ego.
A person is a person, much the same as you. If they do their best to complete their work in life, if they do not bring harm to others, if they wish for only the best, how can you fault them? So what if they don't have designer clothes and a fancy car, this does not make them a less worthy person.
A day does come where we all must atone for our sins, how long is your list? Give a helping hand, be a friend, look at the Soul, not the outside decorations. Every step that we make is known, every thought that we think is known. Always know, you are never truly alone, your creator walks alongside you.
