Okay, so I'm a pretty outgoing guy. I'm not the shy type at all. But I can't for the life of me start a convo with a random girl. If someone introduces me, I'm cool to converse, no problem. But to randomly approach, I can't. I don't know what to say. They'll usually give one word answers for the first few things you say. I don't know how to progress without it feeling awkward (which is a bad sign) or thinking it sounds stupid. I know there are guys who have no problem with this no matter the environment. Any advice?
