Paul and I leave notes for each other all the time..
Kind of like the "new game" we're playing here.
I start a note and then a few days later
I'll find it with an added message on my desk.
I'll wait a few days and give it back to him. Back and forth it goes. Kind of silly but it's always so nice.
He just told me that he's kept every note and card that I've ever given him! Locked up in the file cabnet. I thought he threw them all away. I knew I kept every thing from him in my memory box, finding out that he's keeping everything too really made my heart smile. When he goes hunting next time he's going to give them all to me so I can re-read them. I'll have a blast remembering all the good times.
