Short accounts and long fuses are a sign that something sinister is beneath the surface. They are the pimples of the soul. Where that kind of gross is coming to the surface, a worse gross is growing in the darkened corners of the inner life. The only solution is to grow in love and that only way to grow in love is to stop focusing on what irritates you about others and to remember how irritable you can be and how loved you are by others even when you are. If you can consider how much grace it takes to put up with you, you will find the grace to put up with your annoyances with others. If you won't eat your food without a layer of thick blame sauce and a side of thin love soup, you are going to starve your soul to death. But if you realize how thin your excuses are and how thick your head is, you will begin to appreciate others. You will be forgiven and you will look to forgive others.
Luke 7:47
Wherefore I say unto thee, Her sins, which are many, are forgiven; for she loved much: but to whom little is forgiven, the same loveth little.
The one who knows that they have been forgiven much and are owed very little with go to great lengths to overlook the offenses of others and to pay the cost to love others well even when they do not deserve it... as a matter of fact, especially when they don't.
Luke 6:35
He is kind unto the unthankful and to the evil.
