Re: Oliver and Harry and Susan
At first, Harry wasn't sure what to do. Should he leave? Did Susan want to be alone with Oliver? They were flirting pretty obviously, and he didn't want to be a third wheel. But he also was having fun watching them, and they hadn't excluded him at all. This was a case where he was over thinking things, he decided, and wondered when that had become his habit rather than rush in headfirst.
"Oliver wants everyone to find him cute," Harry said, chiming in at last. "And for the record, I wasn't the only one laughing at Perkins. He really should learn to check where a box of chocolates comes from before helping himself." This particular box had been emblazoned with Weasley Wizard Wheezes, and had been confiscated from a jilted bride about to send them to her former-fiances Muggle family.
Awkwardly, at least compared to Oliver and Susan, he began to dance with them.
