Clear your head before talking to her. Dont plan the conversation beforehand, dont think of things you should say. Just head straight to her without thinking a lot, and just be there first. If you can do this then you will have plenty of n things to say at the spot. dont be scared of silence. It's not as bad as it seems. Just greet her and sit there without saying anything until smth natural pops up in ur head. Ask questions and listen to her explain. This is a good trick, she will keep talking
