Where's Emme?

Yesterday I volunteered at the National First Ladies’ Library and after breakfast I went upstairs to get my Abigail Fillmore costume. Of course, Emme came with me. I went to the closet in the green bedroom and packed my suitcase and then left the room to return downstairs. At the top of the stairs I couldn’t find Emme. I opened the door to the bedroom and Emme was not there, so I went downstairs to check if she had dashed down the stairs before me. No Emme. I checked every room and could not find her. I called to Emme as I was looking around but heard no sounds. I went back upstairs and checked the green bedroom again and opened the closet to see if she was shut in there. I was really baffled and then remembered that I had used the upstairs bathroom before I went to pack my costume. Sure enough, there was Emme waiting patiently in the green bathroom. She was standing on the rug and looking up at me. Now, how come she couldn’t make any noise when I was calling her? When she is on guard downstairs, she barks at any movement outside. When I was looking for her and calling her name, she didn’t make a sound. I would think she would have barked or whined but no luck. She just waited patiently and silently for me to find her. Go figure.
