I understand that you have recently returned to Britain. Like you, I myself have arrived back here and have re-acquainted myself with Hermione Granger Weasley. She mentioned to me that you were planning on attending her concert on Wednesday.
Would you do me the honour of accompanying me to see Hermione sing? I could do with some pleasant company for the event.
If this is agreeable to you, please answer by return owl with a place and time we can meet up.
