How to resolve this interpersonal conflict?

This conflict involves my close friend Joanne and I and had happened recently.

During a holiday, Joanne and I were both touring in different countries A and B but we decided to tour country C together and needed to settle on a date.

Being concerned over the prices, Joanne had went ahead to book her own ticket on a set date that was the cheapest for herself. I had no choice but to buy my ticket on the same date too. However I discovered that while flying on that set date is cheapest for Joanne, it is the most expensive for me to fly from country A to C. I was angry and sent an email to express my displeasure. Joanne did give a call to say she was sorry and sounded nice and apologetic. However, I was still appalled by her insensitivity and selfishness and felt that she was only saying sorry nicely because she had already gotten what she wanted.

After that we returned to Singapore and Joanne gave a call sounding as cheerful and happy as ever. However I really found it hard to have a normal genuine conversation with Joanne as the incident is still etched in my mind. However Joanne is probably not aware of this.

The problem is that if I decide to continue with this friendship, how can I resolve this displeasure that I have against her so that we can be genuine friends again? Could I have perhaps failed to consider some things from Joanne's perspective? Or could I have resolved the issue right then and there when the event happened instead of letting it drag on to this day?

Effective Communication Skills are important

Can one ever imagine a life without communicating to anyone, without needing to bring ideas across to people in various social settings, without having to go through a single job application or job interview? Being a shy and introverted child, I used to hope that this could be true! However, I soon realise that interactions between people are simply unavoidable in everyday life.

Every now and then, I am confronted with CCA meetings, group projects and occasionally some networking sessions where I have to make conversations despite feeling rather self-conscious and uncomfortable. Often at the end of the day, I would lament on how I could have just made the meeting a little less awkward and a little smoother. In my opinion, learning effective communication is a journey that has no ending. You can always try to better yourself and still that’s always so much more to learn. Yet I firmly believed the effort is worthwhile as there are times in my life, where a little better communication on my part could have avoided so much awkwardness and embarrassment or even trouble that I later have to fix.

Effective communication enhances the productivity of discussions, leaves one feeling satisfied with oneself and often makes other people feel good about themselves too. Hence I place high value on effective communication and hope to acquire as much of these skills as possible.
