My thinking is - if she starts coming out of her shell a little bit (by appearing talkative) you don't slam the shell closed on her face. Of course I always think back to myself when I was MLC and all I can do is think "how would I have felt if...?" and I know it would have been twice as long before I reached out again...if i did...but that was ME.
It is so hard to say what to do. LD this is where you've just really got to lay down your flesh and seek God's direction. Die to self. It's the hardest and most repetitive thing you will ever have to do on this walk. The things you think and the things you feel...you've got to lay them aside and open yourself up to nothing but Him. That's the only way you'll end up with the "right" answer.
