To continue my "nitpicking" (hahaha!),.....It's a waste of time to continue that with you; I have got some better things to do...c u next time!

It's a good thing for you that I've become Chinese in my outlook due to having been here on mainland for a long time. So, just like traditional Chinese people, I'm able to overlook your terseness and sarcasm to some extent, you being long in the tooth, and therefore deserving of respect.
I have also got some better things to do. No doubt there will be a next time. C u then. Actually, I'm already looking forward to that!
