German?

Tonight while I was folding laundry I was singing the alphabet and then I sang it again in German.  Glenn came up to me and asked me to sing it in Spanish.  I told him that I didn't know it in Spanish that I was speaking in German.  He looked up at me and said, "Uhh?"  The kids only know of two languages spoken in the world, Spanish and English.  They have no idea there are lots more languages. It was pretty funny, the look of confusion on his face.
