Some persons get themselves totally isolated from the society and they like to remain unsocial. Spending life in such a way is not normal.
They actually aren't that interested in making friends.
They sleep a lot and this is an indication that they are suffering from some sort of loneliness.
When it comes to take a bath, lonely persons spend hours in this activity as they have to kill time available to them.
Lonely persons are more likely to suffer from diseases like depression and stress as compared to others who are social.
