Though the event was spearheaded by a committee, there are also many common Singaporeans volunteering for the event, which include the students and others who are looking for jobs. They are deployed in one of the many logistical functions which are required in this grand event.
I feel a tinge of regret not having learnt more on how to go about volunteering for the event. Imagine, if you are able to catch some of the world leaders, like President Obama at close range, this will be an opportunity in a life time! Further, I would really want to do a part for Singapore!
Anyway, I really hope that the delegates will have a nice time in our little country and have fond memories of what Singapore can offer.
