it is very necessary to understand your friend's feelings to maintain a long term relationship, such as, what he/she likes/dislikes, his/her expectation from you.  if you are spending more than 1 hour daily with your friend and you are not understanding his or her feelings, it means you are not a real friend. to maintain a good relationship you must talk to his or her openly. you should spend some times with your friend regularly. you share everything with him/her, whatever you are feeling. due to lack of regular communication, the distance between both starts increase slowly-slowly. and it is not good.
