A Game to play in the library

I finally thought of a something to do in the library when you're sick of studying. Is best when studying for those kind of fact-memorisation exams i.e. history as opposed to maths, where u need to keep repeating a series of facts over and over in your mind.

Keep staring a girl who is facing u, at any table u choose. As long as she can see u when she look up from her notes can liao. Stare until she look up. And when she does, maintain the eye contact until something happens (e.g. she walk over to you and ask for mmmff mmmpph mmfff) or more likely, she abruptly breaks the contact and looks back at her notes. When this happens, go on to the next girl. Repeat until you have finished doing so for all the girls facing u.
