It's all about nostalgia. The lyrics talk about the harsh end of adolescence and the transition to adulthood and how they miss the good and simple things of the past, when life was much easier.

(...) Richardson has worked with big cats and relies on intuition rather than static rules. He has slept next to, fed, and lived with lions. Along with lions, he has worked with cheetahs, leopards, and hyenas. He prefers lions to any other big cat. His relationship with the animals, however, has not been an instant one. He has known all of the lions he works with since they were cubs. He still continues his bond with Tau and Napoleon, the lion brothers who were his introduction to big cats.
