I should feel bad, but I drove my mother's old pick-up truck without my mom's permission.
You don't feel bad for driving it without her permission?
I felt bored and I wanted to drive it
Even if it belongs to your parents, you should ask for permission. Otherwise you could get in trouble with your parents
I don't care, I feel like testing my luck.
I think you should take a few moments to think about the repercussions of what you're doing. If your mom wanted to punish you she could pressure charges for such an act!
