After a couple days reflection of my own, I realize that last post probably came across as insensitive. You never really know what's going on in someone else's head, on or offline. One positive outcome of good Tai Chi Chuan, meditative superpowers. Sometimes it's just a matter of time and breathing, maybe little pain of your own, to help you see someone else more clearly. My apologies Xue. Hope we see you again! Best of luck with your Kung Fu. I know it's how I get through my own days.
