President Obama does not have warm personal relationships with other world leaders. Another world leader is Xi Jinping of China. Obama does not have warm relations with Xi. Xi and wife travelled to California to meet Obama. Obama did not have his wife with him. The Chinese were offended.

I have had personal relations with Chinese. I have offended Chinese forreasonsIhavenoFRIGGINGideawhy. I would have known to have my wife, if I had one, which I don't, which is good, in which case I would have known to have a wife-like being, with me if a Chinese man and his wife came to the US to visit me. Which they haven't.
