LOST KEYS

So Last night I went to a meeting with my parents at the Hampton Inn and Suites in Orem.  I remember locking the door and than I thought I put them in my purse and got in my parents car.  I went to the meeting at the Hampton Inn and then I rode with Timmy on the way home.  Timmy unlocked the door to the apartment so I didn't worry about pulling out my keys.  I walked in and set my purse down on the chair in the kitchen.  We ate banana cream pie and ice cream with my parents and than went to bed.  I woke up the next morning and when I went to take Timmy to school.. I looked in my purse and they weren't there.  I have looked everywhere... well of course except the place they are.. but I can't imagine them jumping out of my purse.  I checked the hotel.. my mom has checked her car twice and I have looked it places I would have never thought keys could be.  This is the weirdest thing!!  Hopefully I will find them.
