I once had a pet turtle. It ran away.

Turtle, or tortoise? I didn't get a turtle because you have to deal with keeping the water clean, etc.
I had snapping turtles and box turtles when I was a kid - the box turtles outgrew their aquarium so we let them live in the pond in the backyard, and the snapping turtles started biting the tips of each others tails, so we let them go in the river.
I learned last month that snapping turtles aren't actually that aggressive or mean, but they scare easily and try to bite if you get close because their plastron (the chest part of their shell) is quite small, so if they get flipped over their soft belly is exposed.
