Dear Richard Anderson,
We are pleased that you are enjoying the family car that you bought a year ago. It is a great family investment. As for Bill and I, we are hoping to build a kitchen extension. The $3000 you loaned from us would be helpful if you are already able to repay us. We understand if you cannot pay the entire amount, and we could consider a monthly payment that is amicable for both of us. We are inviting you for dinner on Saturday so that we can discuss the payment arrangements.
Sincerely,
Ainhoa
