Something I forgot to tell Serena

I was reading on isotopes until my small eyes weakened, nodding away. So, I scavenged through my small and yet FULLY OCCUPIED table for a bookmark. Then, I came across this...

I was trying to recall who spelled my name wrongly on this lovely 'Green' card. And suddenly, my mind came clear. And I got freshened up instantaneously. So, I started writing... a long conversation.

Last summer, I wanted to know more about one of the climate event happening in campus. I approached this sweet petite girl. Serena is one of the lucky Hong Kong student who got selected for those highly publicised Antarctica journey for university students. A westerner was right behind me when we both stepped in the booth.

I : Hi! This looks interesting to me.
Serena : Hi! Take a look at our campaigns. And the information on the posters.
W : [smile]
Serena : Hey! Do you know what's Climate Change? Have you heard about it? Let me show you here.
W : ok. [looking away fidgeting under the hot sun]
I : [a bit shocked but still manage to smile]

So, Serena was elaborating big time about her adventure in Antarctica with her new friend W. I stood next to her fancy Mac and listened as she explained hyperactively to W all about the Climate and the disastrous changes taking places. Then...

Serena : You can register here if you wish to know more about us.
W : Ok.
Serena : Thank you, W!!!
I : Erm, hey Serena, what's that registration about? Can you tell me more?
Serena : Ok. Just register your details here. [smile, i think it was]
I : Can you show me the English language?
Serena : [puzzled] Ok...
I : Unfortunately, I don't know how to read Chinese [smiled and continued with registering].

W was leaving. So, Serena scribbled something on a card.

Serena : Hi W, this is for you!
W : Thanks.
Serena : What's your name?
I : Teng T-E-N-G. It goes double.

Serena wrote my name on it. First looking at it, and then looked away while writing the one behind. That explains the picture above.

Serena walked away and 'sent' W off.
I went over and told her you got my name wrong. She just asked my name again and then, took her pencil and 'erased'.

I : Thanks [smiled]
Serena : Welcome!

Serena,
THANK YOU for giving me the card.
I am grateful.

You don't have to remember my name,
but I think, you have to remember yours...
