Eyes wide open
Have you ever noticed that sometimes when you catch a persons glance from across the room, you can easily hold eye contact for a few moments but with other people, your eyes have to flit away immediately? There is one guy in class who catches my eye on occasion and we both seem to sigh with exhaustion and mutual sympathy for the learning process. It's like a conversation. But heaven forbid, should I meet eyes with another guy to his right, both our eyes dart away as if we were caught doing something nasty.
