Lock her down means to keep her and cherish her. Treat her right and with the mindset of staying with her or them for a long time. People like you make me sad cause we're supposed to be in the same boat. Yes i have met girls that stutter and they were high achievers that kept to themselves. I also stutter and i always felt a type of kinship with other people who stammer. And when i met someone like myself i didn't tell them I also stutter. Its hard to explain.
