Try this
- Confirm that the item reached you and note anything useful, such as its location or an accessory returned with it.
- If there is damage or something missing, raise that plainly instead of using the thank-you to hide an unresolved issue.
A worked example
“The book is back on my desk, thank you. I also found the bookmark tucked inside.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Future borrowing remains a separate choice. Returning one item does not imply open access to other belongings.
