Really Mom??!?!

We lock Presley’s door at night when she goes to bed. I know it sounds bad but she literally checks to make sure it is locked and if it isn’t, she will not stop getting out of bed!  So we lock it when she goes down and then unlock it when we go to bed.  Sometimes we forget to unlock it and she has to knock to get out in the morning.  Except for this morning.  I forgot to unlock her door last night and as I sat drinking my coffee in bed, I heard her get up try opening the door.  When she discovered it was locked, rather than knocking, she says “really mom?  Really??” 
A few weeks later she was banging on the front door.  I had locked it without realizing she was outside.  When I opened the door, she says to me “WHAT were you thinking!??!”
I was speechless on both accounts.  Someone tell me where this teenager came from!  She’s 3 people!!!
