My Mom has gray hair. Clara calls her "Gi-Gi." Whenever she sees someone with gray hair, she points at them and says, "Gi-Gi." Also, whenever we see someone who looks around the same age as her grandparents- male or female- (but without gray hair), she points and says, "Grandma." She isn't subtle about this, by the way, and some people might think it rude. Well, today she saw an elderly man (probably in his 80's). She pointed and shouted "Grandma's Daddy." Hilarious.
