Morning Message for March 12

Dear Friends,
Today I need your help with a mystery that I need to solve. Last night, I left my special Beauvoir Bear somewhere in the building and I cannot find him. Someone left me some clues below and I need your help. Let me know if you see him around. I miss him!
Love, Mrs. Gibbs-Wilborn

I am inside a room that has a stage.

I am inside a room with an exit door.

I am sitting in a corner of the room.
