Okay so if you’re like me, you’re really mean and use sarcasm way too much. I thought I’d put a quote up that has helped me.

“Be careful also how you indulge in sarcasm. If you are constitutionally inclined to this, you fill find that there is no point in your character which needs to be more faithfully guarded. There are some few cases in which severe irony may be employed to advantage–cases in which vice and error will shrink before it, when they will unhesitatingly confront every other species of opposition. But it too often happens that those who possess this talent use it too indiscriminately; and perhaps even more frequently to confound modest and retiring virtue, than to abash bold and insolent vice. But be assured that it is a contemptible triumph that is gained, when, by the force of sarcasm, the lips of a deserving individual are sealed, and the countenance crimsoned with blushes. And there are only a few case– cases in which the cast of character is peculiar–that will warrant the use of this weapon against vice itself. You may take it for granted, in all ordinary cases in which a sarcastic remark has done it’s office, that you have excited feelings of no friendly character towards yourself. You may be flattered by the compliment you imagine those around you are paying to your wit, but it were more reasonable for you to grieve at the reflection that you have improbably lost a friend.” –William B. Sprague, Letters to a Daughter on Practical Subjects
