Matt is quite a friendly boy, he loves everyone and thinks everyone deserves a second choice. He's very sweet, and helpful. He's gentle, with emotions, with people, with basically any living being. He is quite honest and has strong morals he follows, though wouldn't harm anyone to get what he wanted. He is overall quite a nice, social person to be around with.
However, with these traits come bad things. He is sensitive, easy to make cry or get out of your way. He's easy to manipulate and be used. He's weak, and won't really fight back, as he doesn't see it's justified. He's very naive and won't notice bad things until it's too late. You could simply use different words and trick him into anything.
Overall he's easy to trick. A sweetheart to everyone he knows. Rather harmless with inflicting damage. Very loving to everyone, even people who don't want/deserve it. He wants happiness and does everything he can to spread it. He's naive, quick to trust, and able to be pushed around without even knowing it.
Matthew McKnight was born into a muggle wizard family with two wizard parents, Hellen McKnight (nee Roberts) and Thomas McKnight. Matthew McKnight was a long going Auror for the American Ministry. Hellen McKnight was a wizard painter, and they fell in love right after graduating from Ilvermorny. They got married and had Matthew at 26 and 27.
They brought him up in America, being sorted to Thunderbird at Ilvermorny. He made a good friend, Percy Kingsley, who's family lived next to him. They immediately became closely bonded best friends. At the age of eight, a group of three boys had been beating Percy up. In a burst of anger, he almost choked one of the boys with his magic, before the other boys ran for help. Matthew grabbed Percy and ran.
The Kingsley's eventually moved away to Britain. Matthew was quite sad, as sending owls all the way to Britain would be hard, so he barely wrote. He spent most of his days studying, reading, being an Ilvermorny and learning a lot. He read up a lot about old American wizard tales and quite enjoyed them. He spent a lot of time practing Potions and Herbology, aswell.
When Matthew turned 15 his father had to be brought to the British Ministry of Magic for important business. So the McKnight family packed their things and moved to Britain. He was accepted into Hogwarts. He went and got his things at Diagon Alley and prepared for school. His first goal is to meet up again with Percy Kingsley when he can.
