That does make sense Tatertot!
It's been my experience that I have learned more from my own mistakes than from someone intervening on my potential bad decisions. Know what I mean?
Sure - it would have been nice for someone to warn you about the Coke Zero... but boy, didn't you learn that lesson well?!?!?
I guess to add to it... yes it would be nice to have someone warn us... but it's not their responsibility to warn or protect us from something that's harmful to us. That's our job - and our job alone!
