My DIL of three years calls me Mary, and that is fine with me, I want her to feel that she can call me that and it doesn't hurt my feelings. When she talks about me she refers to me as her MIL. My SIL has a hard time calling me anything, he feels we are to young, he is forty-five and my daughter is thirty eight and i am 58, he has issues, lots and lots of issues and i wish he would fall off the face of the earth. My other son is not married but is seeing an exceptional young woman and I hope they will get married, they are both still in school and want to get their degrees first. But she calls mom, and she is a doll
