Responding to life like a mature adult

Guy took up two parallel parking spaces so I had to ask him to move up. (Parking is very hard to find here) He did, barely, and left me just enough space to fit behind him but it was tight. I come back to my car and he was gone, but had left this for me. He made it out so idk why he was so angry. I could only think of one appropriate response...

I shall carry this with me until the day I see his car parked and waiting for this note.
