When I was a teenager living at home with my dad, it always felt like he was invading my privacy.

He would do things like open and read the mail that I got.

Or he would go into my room when I wasn't there.

He says he was picking up trash or collecting dirty cups,

but I always suspected he was going through my things for some reason.

Sometimes he'd barge into my room when I was there too, and I didn't like that.

What if he saw me doing something on my computer that I didn't want him to see?

So I set up an early warning system, so I would know when he was coming.

I would sometimes put sheets of newspaper just outside my door.

I'd arrange it in such a way that he'd have to step on it to get to my door.

And the crinkle of the newspaper would tip me off that someone's coming.

This worked for a while, especially just hearing him complain,

ah, there's newspaper all over the floor. What's going on out here?

That way I wouldn't know he's coming in.

But one day he decided to be tricky.

He wanted to come in my room, but didn't want to make noise with the newspaper.

So he came up to my door very slowly and quietly,

and gently picked up the newspaper so that it didn't make a single crinkle noise.

With the early warning system deactivated, he opened my door and came right in.

I was sitting in my bed reading one of my school box.

I was baffled that he didn't trip my alarm, and I asked,

Dad, how did you get in without the newspaper making noises?
