Cat in Window

Here is the story to go with this picture:

This cat once had his leg injured, and although he's normally fine, I have noticed that he doesn't seem to do as much jumping as his brother. Specifically, one day he wanted to jump up on the windowsill but he couldn't quite go for it. He sat up and gazed at the window, he ran back and forth under the window, he mewed, but he didn't jump.

Meanwhile, his brother was sitting up in the window and decided to come down. He could jump, but he's too lazy. Instead he climbs down by way of the couch.

On this occasion he noticed that the other cat wanted to get on the windowsill. So he stopped with his front legs on the back of the couch and his hind legs on the windowsill, and stared at his brother. He waited until his brother saw him up there, and then he very slowly climbed down. He was obviously showing him how to do it. His brother observed this, came over and climbed past him up to the window.

Now they can both sit up there--as long as I have the window open.
