Helping a Friend
Dear  [Mentat],
I just returned from the post office, and have sent you the $500 you requested to borrow. You should receive this tomorrow (Saturday) before noon. It cost $12.25 to send with insurance. So you owe me $512.25 total. Hope this gets you by until your SSI issues are straightened out, and I’m very glad I could help. Let me know when you cash it or if it fails to arrive when stated.
Tom
