It is said that the eyes are the mirror to a person’s soul, by looking into her eyes you are creating a moment of intimacy. Friends don’t usually make long eye contact. So, look into her eyes for a tad longer to “tell” her that you want to be more than just friends. Make the eye contact at some point when you are both conversing with each other. Hold it and let the eyes do the talking!
Remember that this is not a staring match though, so don’t stare. Be subtle so that she will feel uncomfortable. Don’t just stare at the floor when you are talking to a girl.
Although many guys feel more comfortable counting floor tiles as opposed to looking at the girl they are conversing with, it can be overcome if you start practicing making eye contact during interaction. If you avoid eye contact during conversation, women may perceive that you have something to hide!
