Here is Toby desperately trying to get Annie to take him outside. First he got her shoes and took them to her. Then he tried to get her feet into them.
He tried passing them up to her. Finally, he was excited to have the opportunity to hop on her back (still wearing her shoe on his arm).
He gets on her back like this any time she is within reach. Even if she isn’t moving…. he just waits there…. hoping she’ll take him somewhere interesting.
