Message in a bottle

So I was away on my girlfriends parents boat for a week and just after we left Rhum we found a message in a bottle, we caught it and my girlfriend took the address and name from the message and plans to write back. It was a 10 year old girl who had been on holiday and sent it - as you do at that age - we are going to reply and see how she reacts! The picture shows my girlfriend throwing the bottle back out to sea with the original message inside!
