“"Yes John?"”

“It's the second one because it is smaller and has better chances to climb and to escape predators”

“"That's absolutely wrong! In fact this one has both advantages. It's stronger and the colour in his face makes him more attractive to females"”

Your heard almost stopped beating! It was wrong...

Suddenly your cage shocked you and you couldn't help but moan a little bit. It hurted so bad...
