One time a friend and I hunted an old lady with turtles.
Why did you dress up as an old lady?
We didn't dress up as an old lady. We just borrowed one of her turtles.
Taking someone's pet with out asking is not right. The woman might get worried and try to look for her turtle. Do you think she might experience mental anguish?
Turtling is a good hobby for her. She obviously doesn't enjoy tortoises.
If you take her pet what happens if she goes around looking for it and  falls and gets hurt? Have you ever asked her to see if you can play with her turtle in her yard or something?
