Maturity

For the first time yesterday, I had someone say something that went against what I have heard since I was in elementary school. I have always been told I was mature. Mrs. T and I went to lunch yesterday and talked about what had been going on in my life lately. She told me that I was dealing with things I did "not have the maturity to handle." If I remember correctly, she implied I was not old enough to have the maturity, but I am not sure. No one has ever told me that before. Everyone tells me I am mature for my years, "an old soul." I don't know how to react.
