But if you are around people that do, please don’t tweet it.
To be clear, I'm quite nice to people who deserve it, and to people who haven't shown anything either way (i.e. I am nice to strangers whose personalities I simply do not know). All I'm saying is that I feel no need to accommodate jerks. It's strange that society has conditioned us so strongly that such an obvious statement is seen as shocking.
I generally don't care if you're talking at the next table over and I can hear what you say, although I'm happy to be entertained by it if it's amusing. However, I think it's idiotic to be at that next table over and then be shocked, shocked that the information you're broadcasting is actually being received by other people.
