Felicia squealed with surprise as Bobby shoved her. Shrieking, she twisted, grabbing at his arm to stop her descent into the cold, dark water. But no such luck. She hit the water with a splash, disappearing beneath it.
That was the thing about luck. Sometimes it struck when you least expected it. Like when Bobby pushed his weight forward to shove her - his sandal just happened caught on the space between the dock's wooden boards, pitching him forward as well. Bad luck, Bobby.
