Embarrassing moments...Part VI

Is it actually possible to remember a blunder way back when you were 5 years old? If you are like me, yes, absolutely.
The year is 1974. The place: Galliate, Italy, about 30 miles outside of Milan. My family was living on the top floor of an apartment building. One floor below lived my best friend, Cristina, and her family. Our mothers were friends, so we would hang out together every day after school and every weekend.
On this day, my mother and her friend were having afternoon tea and cookies, Cristina and I decided to play in the living room. We were both really into Barbies back then, as most little girls are. We would spend hours playing dress up, inventing little stories and play-acting. We had already played "Barbie is a model", "Barbie is a princess", "Barbie is an actress", "Barbie is a bride" and others, when we decided our Barbies were decidedly more serious and therefore needed to have a better job. After talking about different positions, we determined "doctor" was probably the best.
We had been playing for an hour or so, when I suggested it would be fun to play doctor with ourselves. Cristina had a toy stethoscope, so we took turns listening to each other's heartbeats. One thing led to another and soon we both had our pants down, inspecting our nether areas. My mother walked in just in time to catch Cristina lying face down on the couch while I was inserting a pen up where the sun don't shine, trying to take her temperature.
My mom let out a high-pitched scream, ran towards me, pulled the aforementioned pen out of Cristina's behind and dragged me out of the room by my arm. She told me: "Just wait 'til your father gets home, you are in so much trouble!"
I had no idea what the heck she was talking about, I was just 5 years old...but I knew how to play the game.
I got in my pajamas and waited for my father on the stairs; as soon as I saw him, I immediately began crying and apologizing, knowing it would be impossible for him to spank me, since I was already crying.
When my mother told him what I had done, he laughed.
Once again, I had escaped unscathed.
