Serious answer: Depends on the situation. Eye contact is one of many aspects to communication. If it's a woman I'm attracted to, I try to combine my eyes and general facial expression with my vocal inflection to make a flirtatious impression. If it's a confrontational situation, I relay my inner calm and lack of fear through blank eye expression to help the antagonizer understand that I'm not an excitable victim. If it's a friend, my eyes are just the things above the stupid smirk I'm making while I talk shit and make stupid puns.

Knowing how and what amount of eye contact to make is a pretty serious part of communication, kids. So, take that into consideration for both professional and personal use.

Reddit recycled answer: Eye contact? I can't do that; I'm a Redditor and don't have social skills. Amirite? - insert overused meme here -
