Letters in my phone

The written word is more powerful than anything and fortunately my friends and family know this too well. In order to fully communicate with me you have to write things down due to the fact my attention span is about 3 seconds. This has lead to a minuscule revolution in my phone case. Currently there are 5 notes in the back of my phone from friends and family. it is a simple idea but it is effective. They cheer me up and surprise me because i never know they are there until i stumble upon them. (even if it means my phone case often topples off)
