Hopefully now you have written a letter your family should understand. The above suggestion is a very good idea, although even signs like this can be ignored. I have a friend who has a very large sign on her mare's stable which reads 'DO NOT FEED ME TREATS!'. We still catch kids giving her polos!
I hope Comet will be OK and you don't have any problems like this in the future. X
