"I've changed my mind, everyone unpack! We aren't going to let those freaks chase us off our property!" The fat man shouted.
Harry was sick of the constant yelling more than Uncle Vernon's ever changing decision, and decided it was time to end it.
"Uncle Vernon, you know I'll be seventeen soon, right?" Harry asked sweetly.
"So what?" Vernon nearly snarled.
"So I will be able to use my, how did you put it, freakishness without problems." Harry withheld a grin as his Uncle paled.
"You wouldn't dare boy." The fat man blustered.
"Of course I would, I really do feel the need to show my appreciation for treating me so... kindly." Harry wouldn't do much to them, really, but they didn't need to know that.
The Dursleys left and were never seen in Little Whinging again.
