metaphor

The excitement of the children in the game room can be compared to a zoo. The children are everywhere, all types and all ages. Touching everything in there way. Some cant help but stop and ask me lots of questions: others play games like pool, foosball, and even games on the computer. Yet the excitement on the playground can be decribed as an out of control zoo, kids are running around everywhere like they where free from confinement. Just like the animals of a zoo would if they were free'd, filled with joy and excitement.
