I don't know if it's because I'm a cold-hearted meanie, but I love it when I go to the kitchen or bathroom and Sunny loses track of where I am and starts searching for me. I never start this on purpose but as soon as I see her fast trot to the other rooms and peeking in I know what's up and I like to prolong it a bit more because she looks so darn cute searching for me! I have an island in my kitchen and we'll often go around it in circles. But she's pretty smart and I have to stay quick on my feet because she changes directions sometimes! I never do this more than a minute or two but because I know how desperately she searches for me when she thinks she's lost me, I always make sure she clearly sees me when I actually do leave the apartment. And a couple treats left in her bowl and in a treat ball help ease the separation anxiety!
