Gee, I didn't feel old when my only grandchild was born. (I was 54 and thrilled!) Just teasing-- you didn't offend. Mine calls me Grandma, and sometimes lately Grandmother. (She's 11, at an age when that makes her feel grown up.) I don't mind either. My grandma was a treasure. As I've heard others say, she can call me whatever, as long as she calls often.
