Do you know anyone who is always sarcastic and never anything else?

Do you have any people in your life who can only make sarcastic remarks, rather than engaging in other kinds of conversation?

I like a well placed sarcastic remark as much as the next guy, but I find it very tiresome to hear only sarcastic remarks, rather than having real conversations, or being serious when a situation calls for being serious, or even employing other kinds of humor that adults can understand and appreciate.

To me, sarcastic remarks are kind of like the pre-teens of the world of humor, the txt spk of the world of words. Sarcastic remarks can be funny and cute, when employed at the right moment, but when they’re used excessively, and to the exclusion of other forms of communication, they’re just annoying.

Have you ever been able to steer an excessively sarcastic person into other forms of communication? If so, how did you do it?

Believe it or not, I am not trying to be silly (or sarcastic) in asking this question, that’s why I’m putting it in General.
