Today, long after ten years ago when I answered the door to someone asking if my mummy and daddy were home, and I was 24 and it was my house, I just now got asked if my 30 year-old sister was my daughter. Time has not been kind to me. FML
Just get a wig.
Today, while picking up my 14-year-old sister, a friend of hers ask if I was her mother. I’m only 17. FML
Don´t worry. They probably thought your sister looked like 2 years old and you became a mother at 15.
