Have to know where my sister is.

If Nelli is out with me or Otto Peppi often crys inside. As soon as Nelli comes in she is happy again.
Today Nelli wanted to go out but I didn't have time or interest to go with her, so she went to the terrace in a box. Peppi was sitting behind the door and crying some times. Then she went to their climbing tree which is beside one window and tried to see Nelli of there. It looked funny because she were streching herself to odd position..
So I got an idea to put a chair next to the door so Peppi can see Nelli all the time. :D
She was happy again.
