I think I screen peeked as a child.
I don't understand; what is screen peeking?
I've seen something I wasn't supposed to wind up seeing on the tv.
As a child you didn't know any better. Children break the rules all the time.
What? I didn't know I was being a bad kid.
You're right; kids do things all the time that they don't understand they shouldn't. It is normal for kids to be curious, especially about what is on the tv when their parents are watching. Being sneaky is a normal part of childhood.
