Disagreements are invasive. They invade your thoughts as they replay in your mind what you should have responded. The right words allude you at the time you most need them and then echo in your thoughts throughout the days and nights to come. I don't necessarily avoid disagreements with some people. They are the way we can sharpen each other and find out exactly what the other person thinks. It has changed my mind more than once.
But there are days when disagreements can suck the very life out of you. This is when not only do you realize you do not see eye to eye - but when you realize that the other person does not even care what you think or feel. Those are the disagreements I like to avoid. They are not productive and will never move us in a place of a closer relationship. Those kinds of differences only further polarize us from each other and then threaten to break any relationship we might have had......even if it is through blood.
