Brooke Mills is just like the countless other students who can’t wait to take a “first day of school” photo at the beginning of each new academic year.She and her mother went outdoors to snap a picture on the first day of seventh grade.Mills and her mother were outside taking pictures by a tree when they were interrupted by an uninvited guest.A number of shots had already been taken, and everything looked wonderful. Mills’ mother then noticed her son.“It blended so well I looked harder and realized what was there,” Joy Mills, the girl’s mom, told The Dodo.There was a snake, stretched out on the tree trunk, looking straight at the preening seventh grader.Mills’ mom told her to come over to her right away, and at first she didn’t understand why.Because her mother didn’t want to frighten her, Mills didn’t find out about the snake photobombing until she was safely away from the tree.She didn’t realize she was sharing her joy with an improbable companion.“When she realized what was behind her she was speechless,” Mills said. “We couldn’t believe it when we looked at my phone at the pics and just how close he was and we had no idea.”Apparently the snake was envious of all the attention Mills was getting and decided he needed some of his own.Mills will have the best back-to-school photos (and the best tale) in her class thanks to a friendly snake.
