The ancient Greek philosopher Aristotle, who lived 2400 years ago, realized that humans cannot live in isolation. Humans need social interaction to fulfill various needs, including basic needs such as food, shelter, and also the need for security, affection, and recognition.
Humans are zoon politicon in Greek, or social creatures according to Aristotle's conclusion. This is because humans cannot fulfill all their needs on their own, they depend on others in various aspects of life. So social interaction, whether directly or indirectly, is an integral part of human life.
Building friendships, friendships, can make one's existence more recognized. Without recognition, a human being is a number, if related to the context of today's life, a human being is nothing more than a row of population identification numbers. A cold, meaningless definition.
On the other hand, God equipped humans with feelings, regrets and emotions. Not only reason. With feelings and emotions, humans have feelings that trigger them to like, to be happy, to be happy, to have memories. If it is related to the discussion about humans as social creatures earlier, then the pleasure of being together, the pleasure of interaction, is the essence of social life itself.
The togetherness that then creates an image of the beauty of interaction, settles collectively, and will always be beautiful when it is talked about again by each individual who is a member of that collective memory, when they meet again after a long time apart.
In today's changing world, friendships that have been made, then forgotten, will always be a topic of conversation that makes you smile. So reunion, in this context, is not just a gathering event, but also a means to strengthen social relationships that have been established for a long time. That's where, when a reunion is held, friendship and memories become a separate pair.
On the other hand, a friendship that has no memories is just a soulless relationship, like clouds in an aquarium without water and air. Pale and dry. Celebrating friendship, then, is an activity that will probably always be fun for most people.
Friendship celebrations must be tested by time, whether your former friend still misses you, to remember the past. Friendship celebrations are also a symbol of friendship work, a piece of worship that God has commanded to be maintained.
