My mother and I are cookie cutter images of each other, including how we look. A sister of mine once saw her at her place of work (had no idea she was my mom, we have different last names so that couldn't be it) and called me saying, "Does your mom work here and is this her name??" because she said she looked EXACTLY like me.
About the only way we are different is that she is MUCH more patient than me...but I'm hoping that will come with time
