I believed that babies spoke their own language, that only mothers could understand (the product of watching mothers trying to guess at what their children wanted when they cried, I guess). Once, when a family friend was at our house with her baby, who was babbling away, I asked my mom to translate for me. I guess she was too busy to talk with me, so she just kept saying "I don't know what he's saying." It was a while before someone explained to me that babies don't actually talk yet.
