The two of you, Paul and Tang....
You remind me of what I call "The Story of Naydi." Naydi is a friend of mine, married. She wanted her husband to do something for her, and at first he didn't. She got pissed off, called him out on it, and eventually he said he would do it. Now, though it wasn't good enough for Naydi, because he didn't say he'd do it in a particular way, his tone wasn't kind enough, or whatever it was that bent her. So, said "just forget it."
The point is, Naydi was more committed to being right and upset than she was with having her husband do what she wanted. He ultimately gave her what she wanted, but it wasn't good enough.
Tang said he would take care of it. But that's not good enough for Paul. Should we come up with a plan to punish Tang? Should we beat him? Or do you choose to reach for forgiveness and let it go (and let him make amends)?
It's a choice. There's no right or wrong in it. But life is TOO FUCKING SHORT for this kind of bullshit, folks. For fucks sake, wake up.
