A random stranger, that is.
I was walking home from the library today, toting my wheely cart filled to the brim with books, when a guy drove by me. He turned around, heading in my direction again and I went into my typical paranoid mode, thinking he could be a serial kidnapper/murderer. Completely logical, I know.
As he approached, I turned to make sure no crazed human was jumping out to grab me. He slowed down beside me and said, "Excuse me, miss, are you single?" I responded with a "no, I"m not". He said, "Oh, okay. Well, you're very cute." I smiled and said "thank you".
He totally made my day!! =)
