Several years ago during a heated conversation that I was having with an ex-girlfriend she told me that "no one will ever tolerate [me] the way that [she] does". Aside from the several other things that were said in the course of the fight this one statement really stood out. I never thought of myself as somewhat that needed to be tolerated in order to be with me. For several years I believed that I was so intolerable of a person that I was a burden as well. Well, here I am years later and I realize now that what that ex said to me was the biggest "fuck you" I think I've ever heard. The memory of that argument was stirred the other day at a work lunch when some of us were asking some personal questions. When two people that I work with stated that the most important attribute of their partner from their last relationship was that they were tolerant I got a little worked up.

Miriam-Webster's definition of tolerance:

1 : capacity to endure pain or hardship : endurance, fortitude, stamina
2 a : sympathy or indulgence for beliefs or practices differing from or conflicting with one's own b : the act of allowing something
