How old are you?

"Oh, you!", she spoke in tongues. He could see through startled hesitation running across her glossed face despite efforts to sneak them. 
"Want to have chocolate?" He nodded like a child to get cadbury wrapped in pink. 
"We hope to see you in Japan," a lad's voice ended his gaze at her.
"Y..ye..es, of course," He replied in stammering voice.
The short conversation brought a vista of memory in his mind. His mind could not stop recalling what had happened a week before.  
It was dusk and a kind of breeze with cold texture. It was his black jacket keeping him warm from Irish cold weather. The weather would not be cold early in his country. Might be, its a more of his age than the weather!
A voice from the back stopped him though it was not any of the one he had known before. Would he have paused had there been any male voice? I didn't know. But he stopped! 
"You must be from China," he said in assertive voice as if he was an expert in making out people's locating from their speech.
"A bad joke," she responded.
"Then, I am at least good at bad jokes." He waved his collar taking it as a complement. Next moment, some instinct made him say, "Konbanwa".
That was a surprise for her. Next moment, she came with arms wide to hug. A moment, may be five minutes! He didn't know exactly.
Then, she asked in whispering voice, "how old are you?"
