You are not very good if you are not better than your best friends imagine you to be.
Never make assumptions about people.
I like the prayer which says: Lord, make me the person my dog thinks I am.
Why does your dog have a higher opinion of you than your best friends do? Maybe it's because your dog asks no questions and makes no assumptions.
There's also a song: "Nobody knows the trouble I've seen." Even our friends, who know more about us than our dogs, don't know the real weight of the burdens we carry around with us, the pains of the present and the past, dreams we cherish for the future and the fears that lurk in the dark corners of our minds.
Even worse is when a friend underestimates us, places us on a lower level of experience, knowledge and ability than we rightly deserve. Overestimate me and you are liable to hurt yourself. Underestimate me and you hurt me.
I have sometimes had to redefine my relationship with people who persist in wrongly patronizing me about things they have no knowledge of. I've also lost friends who made wrong critical judgements about me.
I once had a friend who believes that I made a long and expensive call on his telephone. We knew each other for many years. Why he would assume that I made that call without telling him and, certainly, reimbursing him for it is a mystery, as is his continuing belief that I lied about it. I still care for that fellow. We were friends. But so be it.
I am a better man than he thinks I am and I know it, and since I have no dog to back me up, that will have to do for me. Which it does.
