When I am working I leave my office door (in the back yard)
ajar. It closes, but isn't latched.

Little Annie comes and goes all day. She just did it - pushed the door open with her feet - walked in and came over to me.
She put her front paws on my lap and said "hello" - got a scritch on the head and soon she was pawing at the door to open it and go outside again.

She does this many times a day - just dropping in for a few minutes to say Hi Mom!

(not too crazy about Annie Butts, am I?)
