An African proverb says that a single hand cannot tie a bundle. Everyone needs companions to help them sail through the rough seas of life. Even the strongest and richest person still needs friends. Our money and strength would have no value if we had no friends to share with us. The best friendship is a give-and-take relationship. We need the support of our family, friends and the community. In turn we also give support to the society, our friends and our family.
The word “friend” has many meanings. It could be the bus driver who takes you to and from work every day. It could be a parent, a colleague, a wife or husband, a brother or sister, or even the unknown person who helped you just once when you could not find your way. Real friends share not only our happiness but our sorrows as well. This may explain why we have the expression “a friend in need is a friend indeed”.
Friendship is like the sunshine that keeps us warm. It is like the refreshing raindrops on the fields that give the farmers hope of a good planting season. Without friends our life would be like a desert where our only friend would be loneliness and sadness. The most fortunate person is the one who has friends from all levels in the society. A driver might find friends not only among his colleagues but among farmers, bankers, traders, students, politicians or teachers. We should never forget our old friends when we make new ones. We should treasure each of our friends whether poor or rich, beautiful or not. Each friend is unique in his or her own way. And all together, they enrich life and make it very colourful.
