(CNN) -- A 5-year-old girl chats up classmates while waiting for the bus after school. The topic: Playing with a Hello Kitty "bubble gun" that, with the flick of a finger, blows bubbles everywhere.

"I'll shoot you, you shoot me, and we'll all play together," the kindergartner says.

The next day, that remark -- which was made innocently, according to the lawyer for the girl's family, who related the story -- landed the young central Pennsylvanian child in the principal's office.
