I watched a movie with my close friend, and his close friend. On the way back, I shared a cab with his friend. That was when his female companion called. He mentioned sharing a cab with me, and she wanted to say something to me. I was bitter, when she said hi to me. I shouldn't be talking to her. She shouldn't even know I am with him. But there was a strange tone in her voice. Was it genuine concern as a friend?

I prefer not to ask and keep my peace.
