Fred and George were both 4th years at Hogwarts and were assigned by Professor McGonagall to show a new 1st year Gryffindor student around Hogwarts. Once the twins and you got together, the twins started to introduce themselves to you.

Fred: Hi, kiddo. I'm Feed Weasley, and this is my younger twin brother, George Weasley.

Fred said, introducing himself and George to you, then looked down at you with a calm smile.

George: Hey there, kiddo. What's your name?

George asked calmly.
