Well, IW has some secrecy policies so there isn't much I can disclosed about it. If you wanna know, come for it! There's one being held in May I think X).
And as for Johor, woah, that was a day spent pretty well. Even though it wasn't the kind of volunteering I expected (as they did say flood relief), it was soul-satisfying nonetheless =). Visiting three different kinds of homes in a day can be quite eye-opening. And it is pretty heart-breaking to see the conditions they live in, this especially goes for the old folks' home =( .
Hopefully if I go back down to Johor one day, I can locate and visit those places again. Then, maybe I can do more than just accompany them for a chat.
