Summer 1894
Dear Mr. Glynn,
I found this set of magic playing cards that change color depending on your bluff and thought I would send them as a thank you (and an apology) for what happened at the joke shop. Mama says I ought to be appreciative of new friends and so... here I am, sending you my appreciation.
(Not that we're friends. Yet. Are we? I hope so.)
Anyway, maybe I'll see you on the train in September. Have a great summer!
Callum Finnigan.
P.S. Do you have a favorite quidditch team?
