Names are important. A name should tell you something about the bearer of that name. Traits, habits, personality, or wishes for that person: happiness, wisdom, joy. In some cultures, the giving of a name is one that takes a lot of time and deliberation. A child remains unnamed until he or she has reached a certain age and a suitable name can be chosen or acquired. In other cultures names are given at birth and at certain special moments in life, either adding to the first name or replacing them.
Here in the Western world we usually don’t give that much thought to a name. We have to give a newborn a name a soon as possible because all kinds of official parties want to register the new human and need to know its name. And most of all, need to make sure it keeps that name. If names were changeable, it would result in total chaos. Or so I’m told.
