What is that sound?

So this morning, we were getting ready and Rusty heard a noise. Then I heard it too. I knew it was coming from outside, so I opened the blinds and look what was staring back at us! Caitlin loved getting to see a squirrel up close and personal. I can't say the same for the squirrel. It had climbed up the screen and then got stuck and couldn't figure out how to get down. Rusty went to open the window to try and help him and the squirrel freaked and jumped to the brick. Not sure how he held on the brick, but he did. We finally decided to leave him alone since we were just making him more scared. Finally, he was able to get down on his own. I don't think he will be visiting again!
