Rudeness?

"Father, she has a name, and she's right behind me." Jingwei said warningly. Xue Ning squeezed his hand for support.

If she wanted to be an asshole, she would have said something like 'don't be too mad at your father, old people often have memory problems.'

But she refused to sink to his level! Her parents taught her better than that. 

Hence, she only bowed slightly to him. If she had nothing nice to say, she would say nothing at all.

Meanwhile, Jingwei could have tolerated rudeness directed at him, but to have Xue Ning blatantly ignored by his father while she was still there, after helping him escape the crowd of reporters. 

She was enchantingly lovely, and he had to keep his back to her for his own sanity.
