Nice, I believe cold reading is one of the best techniques out there. Obviously she was visibly upset about something. Showing women you understand their body language and what they are thinking is a huge DHV.
For example I was talking to a girl online last night. I could tell she was kind of into me but wouldn't meet me. It took me a few minutes and it hit me. I typed to her, "So if I understand right you're attracted to me, you like talking to me, and think about me. However, you are worried about what your friends and family think about you meeting a guy online."
She says to me, "Wow, he actually gets it!" She then follows that by saying, "You're amazing, finally someone who gets me!"
Nice Job!!!
