Dear Diana,
I was friendly with this girl for about a month. We used to travel together in the Metro daily. However, last week, we had a small tiff. I did not realise that she would make such a big deal about it. She had told me to wear a white shirt on that day and I forgot about it. We had decided to be colour coordinated. She was upset and we started arguing. She then walked off in a huff. I did not go after her and apologise. The next day while travelling, she refused to acknowledge me. After that day, though we are in the same train, she does not look at me. What should I do? I sent her a text message saying that I had genuinely forgotten, but she did not reply. I have tried to talk to her, but she does not listen and walks away.
