Search Results: should i approach him

Cold approach is a random guy going up to a random girl, and trying to chat her up. I ask this question because I often see guys talking to girls for 10-15 minutes, and when I ask the guy if he got her number, he said no. I am thinking that this guy is wasting his time, and that he should cut his conversations short. For me, I can sense that a conversation is going nowhere in 20 seconds. People are also generally not very comfortable talking to strangers, which is why I prefer to keep conversations short. If she's into you, she'll give you her number in 1 minute. If not, it won't matter if you talk for 1 hr.
