My wife would tell you that sarcasm is the only way i communicate, however often, it's accidental. I remember as a young teen a neighbor and her newborn were out showing off the baby, mom had a warm proud smile as well as a healthy "glow". a few people said "She's Beautiful!" thinking they meant the mother, I remarked "And the baby is cute too!" which sent all present into loud laughter.. totally accidental, it took me a minute to realize why it was such a funny.
