Hmm.. SS san, do you mean your class sensei gave you this link? Or you are referring to coco san? So sorry that I'm lost in your post. Oh yah! Side track a bit. Just curious where do you learn your Japanese.
Nevermind who gave the link as long as you found the link useful, it's more important.
Coco-san (and many others here as well) is our sensei without doubt. With her kind and modest personalities, even though she doesn't want us to address her as sensei, we should respect her as a "sensei", that is just it should be. Ever heard of 一日為師，終身為父? Coco-san is 母 though
Here's the links to various Japanese Language Schools in Singapore.
Sorry for late reply Terence, been away, just returned home.
