Lost and found re-ward?

Date: 08 Dec 2010
Time: 1040hrs
Place: National University Hospital

I was on my way from the A&E building to the foodcourt when an auntie and uncle asked me in Chinese whether this is the main building. I looked at the signs and told them yes. Then I asked them where they were going and they said Ward 62 and I found a sign for a Wards 20 to 63 and pointed them that way.
