alright, i have a keychain with all my keys on it. (Three car keys and one house key and one room key). anyways, i usually have my room locked at all times. and my parents usually lock the dead bolt before leaving the house in the morning. well i go downstairs to get me something to drink. i go back upstairs, the door is locked. meaning i left the set of keys in my room. sigh, so i get locked inside of my house.
