Damn it. I see whats happening here!!! You're just trying to parade your groovy experience in front of all of us
OFCURSE she is interested. Let me tell you for a fact noone in their right mind would give their number out to a stranger just because they felt like being a little bit helpful. There is clearly some interest there that has to be explored. I guess your next move (If you would like to take this further ofcourse) is to ask her out for a coffee and try to develop some sort of relationship outside of the colledge. Take it one step at a time (Dont rush into anything) and see where this guess...
You lucky lucky person
