my son calls me aunty...

I'm really sad. I don't know why I always feel so inferior to my own family. My mother is a very dominant person... even after I got married and had children. I'm a stepchild, you know, mom. So I already have a child. Since my child could talk, whenever my mother meets my child, she always says, "Just call her auntie. Auntie. Auuuuntie." I once asked her seriously about this... and she said, "Oh, come on, mom's just kidding." I feel really hurt being treated like this by my own family, mom.
