Dexter told Delilah that he is SOOOOOOO tired and he wanted to take a nap in the sunny chair in the living room. Delilah complained to Dexter that she wanted to nap in that chair and she thought of it first.
Dexter responded to Delilah, that he was quicker and got there first; however, there was a bit of spare room on the edge, if she wanted to join him. She agreed and they enjoyed a nice, long and sunny nap.
