Dear FBI agent,
Thank you so much for sending the LAST PIECE OF PAPERWORK that was required for us to finish our adoption homestudy.
Every single day, we faithfully checked the mailbox, hoping you had sent along two quick notes stating that we were not axe murderers.
We appreciate your helpfulness in this matter and are grateful for your attention to it. Once our social worker returns from her much-need vacation, we will be contacting her to deliver your letters.
With much fondness,
