Me and my family - Martha

Martha lives with her twin sister, big brother, mom and dad. They are all def, all except Martha, she can hear and she speaks.
Martha likes to play with her twin sister, and she loves it when her dad tells funny stories using sign language. But Martha thinks it's a little strange to be different than the rest of the family, and she sometimes envies that they have something in common, that she's not a part of.
