All mixed up! Don't know what to do!

When i was little, i was never shy and never embarrassed. One day, i walked into
the schools bathroom when i was about 6, and i saw a girl in there.
She was holding onto the door, and her friend was inside the stall using the restroom.
Now i had gotten there conversations mixed up, and i thought the girl using the bathroom wanted to get outout, but her
friend, who was holding the door, wouldnt let her, but it was the other way around. The friend was tired of holding the door, so she was rushing her friend. and i didnt realize i had mixed up the conversation until now. Haha. But anyways, i ran to the stall and ripped the door open [thinking i was gonna help her], and the girl was sitting there with her pants down. haha. My face turned red instantly and thats when i began to be shy, and was embarrassed sooo easily.
