Re: Is anyone sitting here?
TheDuke has a point. But walking up and just sitting in a strangers seat would freak her out rather than see this guy as confident. UNLESS...you are direct with your interest. Going up to her, intruding her personal space, and just sitting down with the claim that you are hiding from someone is just plain freaky.
If you were to sit down without permission then you MUST be open with your interest in her from the start. Women are approached COUNTLESS times and almost none are DIRECT. They are always trying to be sneaky about "Oh what's good here?" and "Hey do you like to drink water?" (embellished, but you get the point.) It's actually rare for a guy to just be confident, approach her and say "I just had to come talk to you. Otherwise I'd kick myself for the rest of the day."
This is why it is highly advised that Direct Game be used during the day where indirect is more for night game. Even though you can interchange sometimes, it's still the recommended route.
P.S. Never leave immediately after the phone number. Men feel like they should leave because they need to "lock in" what they have built with a woman, but all it does is make them feel like it was a pickup. Always stay at least 5 min after getting the number.
