I already mentionned this guy from who barely knows a word of French. He already walked in Jillian's and my office twice this morning, asking me to translate things for him. (right now I'm translating this document about BLINDS for him, and it's into English as if it wasn't bad enough already, but I must admit it's not that hard.) The funny thing is he seems so embarrassed to make me work everytime, and the second time, he gave me the sheet with about 2 sentences to translate, and he added, in the cutest English accent : "s'il-vous-plaît".
I'd have to make an actual list, but this surely falls into the top 50 of the cutest things ever.
