Then Sings my Soul Sunday: Sarcasm

I'm challenging my young women's class to leave sarcasm at the door on Sunday.
However this will most likely be more of a challenge for my, although improving, sarcastic vernacular.
I love this quote from Gordon B. Hinckley,

"Everywhere is heard the snide remark, the sarcastic gibe, the cutting down of associates. Sadly, these are too often the essence of our conversation. In our homes, wives weep and children finally give up under the barrage of criticism leveled by husbands and fathers. Criticism is the forerunner of divorce, the cultivator of rebellion, sometimes a catalyst that leads to failure...I am asking that we stop seeking out the storms and enjoy more fully the sunlight. I am suggesting that as we go through life we “accentuate the positive.” I am asking that we look a little deeper for the good, that we still voices of insult and sarcasm, that we more generously compliment virtue and effort."

I want my home and my presence to be better than just "everywhere." I want people to leave with elevated thoughts after associating with me.

Sarcasm is however part of our common language. It is often how we relate to one another.

What place does sarcasm have in our lives, if any?
