"El joven que no ha llorado es un salvaje y el viejo que no reirá es un tonto"

Simplified Meaning:

If a young person has never cried, they might be seen as tough or unfeeling, which isn't healthy because crying shows they can feel deeply and understand emotions. For example, imagine a young man who loses a friend. If he doesn't cry, he might seem strong on the outside, but he's really just hiding his feelings. This can make it hard for others to connect with him and can make him feel lonely. On the other hand, an older person who refuses to laugh is missing out on joy and the lightness of life. Picture an old woman who never laughs, even at funny stories or joyful moments with her family. She would seem very stern and might push people away because laughter helps build connections and keep the spirit lively. Both crying when you're young and laughing when you're old show that you’re in touch with your emotions. Connecting with others through shared feelings is an important part of life. So, it's good for everyone to experience and show their emotions fully.
