That's true, and an interesting topic (imo). Both my sons inherited (if you will) my sarcastic sense of humor, and all 3 of my youngest son's daughters got it from him. His youngest daughter's sarcasm is the sharpest, and by that I mean she can be kind of cruel. She never targets anyone with, like, disabilities, or who's less fortunate than her, or in some inescapable circumstance, but once in a while, she hurts someone unknowingly, and then she's all puzzled about it. But then, she's only 13.
I suspect she'll lose a number of friends before she figures this whole thing out.
An example of Ariel's sarcasm and Kat's sensitivities: After Thanksgiving dinner a few years ago, we were all having dessert when Ariel made a wisecrack to her mom about fat. Her mom, who'd been maintaining a weight-loss of over 20 pounds for about a year, laughed until her ribs hurt.
On the other hand, Kat burst into tears and ran into the bathroom. She literally cried for like an hour on Ariel's mom's behalf. And we all looked at each other like "WTF just happened?" (or, in some cases, "The pumpkin pie any good?"

)
All except for Grant.
