So... one goose is not a gaggle. Good thing there are several dozen others just out of the frame that you can't see. You will just have to trust me when I say they were there.
Geese are obnoxious, though. They're sort of cute, but they are very messy and loud and twenty of them will walk over to you when you're just minding your own business, trying to go around town and get some exercise, because they think you have food. Why would I bring my snack on my brisk fresh-air walk when I could just as easily have eaten it in my cozy, goose-free apartment, hmm? Mister Goose?
Anyway, he's sort of cute.
