I think with a cell phone (which I think everyone has these days) it's hard to tell what's happening on the other end. I'm surprised she answered at all, my T had the whole message, "I'll call you back," etc. I'd wait until I saw her in person before I decided what she was like and whether she would work out. Her cell phone is probably both her personal and work phone (and may be a phone others in her family use, my husband and I only have one) so it might not be practical for her to answer other than "Hello." If her best friend calls her on it is she going to want to answer "professionally?"
