I have always struggled with this. I am not a great communicator on a personal level and i dont know where my part is in a conversation so i usually just leave the group or say something weird to the person and say goodbye. I used to be ok at work. I once had to wait at my daughters friends place because she was out somewhere and i had to talk to the friends mum. I couldnt understand why she wanted to tell me about her nephew who called her "mum" because she looked after him while her sister in law was at work. I had no idea what to say and felt like i wanted to leave.
Is there anything to teach me how to do this?
