We may speak the same language though we both interpret the world differently. The human language is a complex concept that all people grasp during their young years. Due to the need to communicate, every toddler begins imitating different words.
Even though they might not understand the words, the undeveloped minds associate words with meaning, same as adults. Nevertheless, words are the most powerful tools of human communication, and without them, nothing we see and do today would be possible.
