One may wait but with a stream of expletives flung at another or one's situation. The litmus test for a person's emotional quotient is the limit in patience and ability to remain silent.
Certain religions prescribe maun vrat, silence, to test one's spiritual progress. Consistency in a display of patience leads one to maintain silence amidst chatter.
Spiritual masters say that without patience, we will learn, see, hear and feel less.
In effect, a person achieves less than possible. Buddhism promotes 'kshanti paramita', the transformative perfection of patience, which lends strength of character and dignity to the person who has mastered it.
