Mood is the reflection of the human state of mind.Everyone has his "blue days".On such occasions,everything seems to go wrong.You wake-up from the edge of the bed.Your partner fails to give you the usual morning kiss.Your children tend to become naughty.As you garther yourself up for the days work,you are face to face with an unwanted guest.You will sometimes observe that your appetite is poor.Your energy seems to be at its lowest ebb,concentration also becomes difficult.And there are feelings of inferiority and irritability.Comments which ordinarily would have been taken as jokes seems to be insults.Sometimes blue mood may result in loss of sleep and at other times it knocks you totally down.Blue days come without warning and most of the time,for no apparent reason.No matter how they come,they are troublesome,and make life miserable,and often lie at the foundation of family quarrels and misunderstanding.Although moods are hard to define,everyone experiences them,for they provide a setting for all conciliation metal processes.Human day to day events have alot of influence on one's mood.
