What's the Number Four on Private Drive?

The dersleys want to be normal, and they want everyone to leave them alone. Privet obviously sounds a lot like private, right? And so i think that that speaks to the desire of the dersleys to live on a private drive. I love also that we're invited to imagine harry alone outside of the house for the first time. He's usually kept inside, or he's with the dursleys when they're on an outing or at school. But here he is, you know, the sof, being alone and free.
