*me mysteriously appears in a puff of smoke*
You guys wouldn't believe this.....
I went off for lunch just now, not realizing that today was a
half-day for NUS.....
When I returned to the lab, it was locked. I had the access
card, but I had no physical key to unlock the door. Worse
still..... my laptop was still inside! 
I asked the research fellows - they didn't have the key. My prof
didn't have the key. And campus security, dumb as it may sound....
also doesn't have the key!
So my laptop will be trapped in there until Friday.
