Ma'am

I stopped by a gas station near my work to get something to drink and inside they had the classic rock radio station playing over the speakers. As I got to the counter to pay, the cashier was telling her co-worker (they were both very young, posibbly still in high school), "oh I love this song!" and her co-worker says "where did you hear this song?" and the cashier says "it was in some movie we watched in class, I can't remember what it is called, but I love this song, I wish I knew who sings it", so I pipe in and say "It's called Don't you forget about me, by the Simple Minds from the movie The Breakfast Club" and the cashier looks at me with a blank stare and says "your total is $1.25 for  the soda ma'am".

I have never felt so old and dorky in my life! I don't know what made me feel worse, the blank stare as if she is saying "butt out" or being called ma'am at 26!
