Question of the Day!

For one summer season a squirrel would peek into the various windows and the patio door of my camper several times a day. She/he would place their front paws on either side of their eyes much like we do when peering into a window. Sometimes when the fancy struck, that crazy squirrel would hang upside down and do this. I'm sure it was the same creature who chittered furiously at me whenever I ventured outside. Could this have been curiosity on the part of the nosey squirrel, or a wellness check of sorts?
