Hello Alli. Welcome to the SARCASM support group.
I can be snarky. I am not sure at what point in I decided that being sarcastic was a good life choice. I would like to say that I was born this way, but I don't think the Lord installs the ability to give somebody a good tongue lashing. Over the years I have honed in on my skills. I primarily use them for good and not evil. Although sometimes I can feel somebody creeping under my skin and the one liners start compiling in my head.
I would like to say that being sarcastic is a fault. But really I am blessed to be quick witted, and light on my feet with my words.
