Who wrote the invitation? Was it the parent or the 16 year old? If it was the parent Mabe"no sharing" means they will leave the decision of who will be drinking up to the other parents. If it was the 16 year old, I think "no sharing" means I will get my hands on as much alcohol as I can for myself so I'm not sharing as I want to get blind drunk. Why are parents condoning illegal activity anyway? I know that 16 year olds drink, I'm sure I did, but not with the approval of my parents. Whats next, do the kids start pulling out their crack pipes and smoking and Mum and Dad say it's ok because everyone else does it and we like to see what our children are doing. I may be a bit harsh but where are the morals and values here?
