It was very fun, although I had to brush my teeth three times after I was done sucking all those sugary lollipops! [It seems like Lockhart really doesn't get it. Although he doesn't mind having his hair stroked, he does give the other boy a bit of a worried look.]

You won't tousle my curls, will you?
