There was no hook. She could be interested, but she could also be nice and answering a 100% neutral question to help out someone new to the city. At some point you"re gonna have to change the topic and go into showing or creating interest, and going from a neutral question to that can be awkward.
As for the other topic, for the purpose of this thread it is pretty irrelevant how much success is in the girl"s hands. You can make sure they"re challenged, which is good both for attraction as well as actually inspire good change in behavior (rarely), but since you cannot control the girl, it"s not really worth talking about. It"s important to keep in mind so you don"t get down on yourself from failures, but it serves no purpose to say "well it didn"t work out...well I can"t control her behavior!" You get way more out of looking at what you may have done wrong, so that you can avoid that error the next time, than looking at the girl"s faults, even if they are many.
