I sometimes think about getting a lizard for a pet.
I would suggest a chameleon or a gecko as a pet, as they are small and change colors.
Maybe it would be too difficult to let a chameleon wander around my apartment, since they're so good at camouflage
I wouldn't let a chameleon wander, you'd have to put him in his own space so you don't lose him! 
Do you have lizards of any kind as pets?
No, I always wanted a Komodo dragon though.. but they can get up to 3 meters long!!!
Oh man, that's way too big for my apartment! Are Komodo dragons violent? or more gentle giants?
Well, they are known for eating mammals as big as water buffalo, so I'd be scared it might eat me.
