When DH and I married, his 2 boys were 4 & 6 yrs old, they are now 45 & 47. They always called me Sally. As they got older and introduced me to others, it was as their stepMother. They would do that right in front of their Mother.

I think they asked me, when they were little, what to call me and I answered, Sally. I remembered when my Mom & Dad devorced and he remarried. She was an A-hole, who went around tell everyone that she was my Mother. I hated her guts for that and told her so..
