Hi, Thanks for writing in. It is best that you consult a psychiatrist and psychologist for a complete understanding of your case. Memory is just one aspect of mental health and there are various forms of memory like remote memory and recent memory. There are also other areas like personality, attitude, mood and interpersonality profile that make you into a social person. There are psychological tests to understand what kind of mental inclination you have. There is a wide range of emotional and mental outlooks and you are certainly normal but might have to change your own outlook towards others. Understanding problems as complex conversations is a logical function and sometimes we are only lazy and do not want to involve ourselves in listening to others. Hearing and listening are different. Hearing is passive and listening is with concentration. So you might not be applying concentration when involving yourself in conversations and missing sentences what has been heard leading to the person your are with unable to communicate with you in an effective manner. All your problems can be solved if you consult a psychiatrist and do some higher mental function and psychological tests. A session or two with psychologist will also help you. Please do not worry.
