H2O Becomes H2-Why?

(I am and have been a referee for two years. One thing I must watch for is if a goalie brings his/her water bottle to the goal with them in case they get thirsty during the game, and make sure the water bottle is behind the goal and out of the way. I am an assistant referee for this game and don’t notice the goalie has done this. The ball ends up hitting her water bottle. Of course, the team I am refereeing is U11 girls, so I don’t expect them to know this law, fully blaming myself for not telling her. During a water break, I politely tell the goalie to make sure she puts her water behind the goal so it doesn’t get hit by the ball.)

Me: “Hey, keeper, make sure you put your water behind he goal so it doesn’t get hit.”

(The goalie nods and does as I asked. A few minutes later, I notice what looks like her grandpa walk over to her and ask her something I couldn’t hear. She replies to him loud enough for me to make out.)

Goalie: “She told me to put it behind the goal so it doesn’t get hit.”

(The grandpa then mumbled something and walked to her water bottle, picked it up, and brought it over to the other side of the goal — opposite of me — and placed it so I couldn’t see it. I just sighed and knew I couldn’t do anything about it. The second half rolled around. The bottle got hit TWICE MORE. Please, listen to referees.)
