I often leave my wife little notes on our whiteboard for groceries. She loves it and I thought I would share the idea. This is the latest one...
"Absence is inevitable
And although they say it makes the heart grow fonder
I don't it need to love you more everyday
And my heart grows fonder of you
Regardless of where I am"
I leave messages along these lines pretty often and it seems to have a very positive effect. I'm going to start posting all of the ones I do in the future. Plagiarize if you'd like.
