Koo Withdrawal

Calvin is having Koo withdrawal. It's not like we used to see her everyday, but now that he knows she is gone, he is talking about her non stop. He keeps telling me that we need to go and see her and tell anyone who will listen that she is in Oregon which is far away. Koo was there when Calvin was born and has lived near us ever since, so he is having a hard time accepting that he is not going to see her for a long time.
