Is this normal behavior?

Is this normal behavior for a 22-mo. old? On Friday, when we got home, I was trying to open a bag of dog food for Bella. And I was struggling a little...you know how hard it is to pry apart those bags?? So Millie saw my struggle and went into the kitchen, opened the top drawer where all the utensils are (which, by the way she cannot see into) and fished around for a second. She then found what she was "looking" for and brought me the SCISSORS! What. How did she know that? We've definitely never taught her that, although we are constantly teaching while we are living. But I was really amazed and couldn't believe that she had put 2 & 2 together.
