Growing up, Percy had heard every insult about their family plenty of times, from the amount of children his parents had, to their lack of money and color of their hair. He liked to think he had become used to it, but in fact, they were sensitive issues for Percy, especially the jokes about their poverty. These insults were what helped propel Percy to get into politics in the first place: if he became Minister of Magic, then perhaps he would finally get some respect. At least that was what he thought as a youth, not knowing the vicious aspects of politics.
Percy looked Greg over again. He knew little of the Goyles, except that they were a Pure Blood family that came from old money. There were several times, when things became chaotic at the Burrow, that Percy had wished he'd come from one of those families, that he was an only child with plenty of disposable income. But the Goyles were also not known for their high intelligence, what to speak of having Death Eater ties, so at least Percy could feel superior in that respect.
"2005," Percy replied, "One year after you. So not that far behind. You managed to keep a low profile in the Wizarding World, which is perfectly understandable.

I remember somebody introducing you on the journals, but I was busy at the time and hadn't been paying much attention to what people were writing."
