Let me get to the bare bones of it all: to get respect, you have to give respect.
To me, respect is the only thing of true value another human being can offer to you. Sure, food and shelter are vital to existence and although it may be offered, you’re setting yourself up to be taken advantage of.
If you have to give respect to get respect, then at least you know where you stand and that’s an even playing field. Once you offer the respect, it is completely up to the recipient to return the notion. If they cannot offer respect in return, it shows their inability to recognize your existence in their life.
But hold your head up, you’re doing your part as a decent human being.
