My friend doesn't listen to me when I'm talking to him he's thinking about something else. While speaking in phone suddenly he stop talking for few mins and then telling me that he forgot that we were talking on that time He was thinking about his work, tomorrows planning and suddenly he was blank he can't remember his daily login password in office. I don't know what it is ? And these symptoms are like ADHD attention deficit hyperactive disorder. But I'm not sure.
