Finding foothold on slippery slope of non-citizenship

I know I'm not the only one feeling a desperate need for acceptance in China. I've been here for a while and I can't get any foothold into the society.

For instance, when I try to give up my seat to an elderly passenger on the buses here in Tianjin, I find myself being gently pushed back into it. I've still got all my hair and teeth - so I can't look as ancient as I feel most mornings - which led me to ask my wife, Ellen, why this happens.

"They're concerned about your safety," she replied with a dismissive wave, but I couldn't let it go.
