So I went out to watch Spiderman with some friends of mine and on my way home I saw a girl on the train. My friend pointed out a tattoo on her wrist that looked like the planter's peanut. I just looked and asked her about it, I didn't even think. I just dived right in and asked her. This led to a conversation between her, my friend and I. I wasn't really trying to pick her up so I didn't flirt too much. Anyway, I was maintaining eye contact and then after a while I noticed how her pupils started dilating every time she faced me to talk. I NEVER noticed that before and it was awesome just seeing that.
