While at camp for the Deaf near Tampico Mexico, I got the chance to talk with Cathy Henning. Cathy has been a missionary for several years. After she arrived in Mexico on her original mission as a school teacher helping Debi Duryee, she started working with the Deaf. Interestingly, though Cathy is an American, she does not know American Sign Language. She learned Mexican Sign Language after she arrived here and has never had need or opportunity to learn the American Sign Language.
