communication is extremely important in any relationship. importance of communication has been stressed upon time and again. lack of communication creates a number of problems that only increase with time.

it is often seen that the families where people talk to each other frequently are happier. they share their joys, sorrows and other emotions with each other. there is a lively atmosphere in such families. they laugh it out together and celebrate every moment whole-hearted. they never feel lonely or bored. they know whenever they want to talk about something or share an emotion they always have an ear to listen to. such is the importance of communication.

compared to this, the families where all the members are engrossed in their own tasks and do not bother to care about or talk to people around them are usually not as happy. the atmosphere in such families is quite dull and gloomy. people are busy with their own tasks. they have friends outside and are not as close with their family members.
