as I think they prove my point even further.
Your first example about the kid being grounded for a day. Comparing a day's worth of grounding to a kid is much different than a once in a lifetime opportunity to play in your backyard when you are from the East Coast. I would say that a better example would be if your child looked forward to a major event all year, maybe he/she was chosen to be one of the main characters in a school play. Let's say that said child has been practicing and working hard and looking forward to this play all year long. Yes, there are other smaller plays he will be involved in, but this one play is very special and he will cherish it for the rest of his life. Does the loving and just parent rip his child's dreams for a crime that is not that significant, simply because "rules are rules." Or, does the loving and just parent choose another punishment that more appropriately fits the crime? Obviously JJ's act was not significant or he would be off the team.
Regarding your drugs with the family example, that is a pretty extreme example. Obviously any drug consumption in any scenario is unacceptable and justice must be swift.
