I volunteered as a belayer/ assistant belayer for height activities during the OBS-MOE open house on the 12th May 2018. I have been through a 5 days 4 nights OBS course during my secondary three. It has a been a very nostalgic feeling stepping foot into OBS once again. This was my first time volunteering in OBS and I look forward to future volunteering events in OBS. Volunteering for this event was definitely a good way of showing my appreciation to OBS. This event helps parents to experience what I had been through for my OBS program so that they have a better understanding of what their child will go through when their child comes for the OBS program. It is also provided an opportunity for me to share my OBS experience with the parents as well as fellow Alumni. I believe what bonded us Alumni and parents who have been through OBS are the shared nostalgia where fond memories were revisited. Even though it was only an event that lasted a couple of hours, I got to forge new friendships with fellow Alumni of all ages. The parents have enjoyed themselves and have bonded well over this event. I have also learnt a few safety aspects, technical handling and commands of being a belayer or belayer assistant.
