So I passed a possum tonight while I was wheeling the trash bin out. It was lurking in the shadows alongside the garage, and when the floods lights came on it kind of just looked at me and gave that "look". Then it got me to thinking, seriously, I feel like possums have only two expressions: one neutral, and the other "surprised/aggressive" (you know, with the wide eyes and gaping mouth). I can't be making this up.
