Communication Problem

Being a single child in my family and studied in famous boys school (St Paul Boys) from 6-16. I was so concentrated in studied and had poor social life. And I have poor communication with my family (my mum loves me, but we never communicate well).

My communication skills had problems. This problem is being magnified in work, my language study and talking with my flatmate

I found out because of my understanding skill was very weak. Evidence to prove this are:
In my japanese exam, although I could translate the text into chinese word directly in the comprehension, I didn t really understand what the authors said, especially regarding the underlying meaning of the text. In other words, even though the text was translated in Chinese, i would get it wrong.

I failed Chinese listening with a grade U (unclassified) in two consecutive years. Even though the test was conducted in Cantonese.

When I talked to my flatmate, I always misunderstood her meaning. She is complaining sometimes. We even had arguments many times because of these small little things..

When I talked to the clients at work. I always misunderstood her meaning and I always ask for summarizations. This is more challenging due to different knowledge between the client and me. For example, the client asks me "You told me that it took 5 minutes to fix it, how come you charge for 3 hours" and My answer is "Yes I took 5 minute to fix it, but I took 3 hours to diagnose the problem"..

I had tried to listen and understand what the other person say.
