It seems to me that the bong has three owners.
It also seems to me that just because you were the (self?)appointed sentinel that you some how lay a greater claim to a possession that has 3 owners.
It also seems to me that you could be angrier at issues that deserve your attention.
To conclude.....
learn to choose your battles.
Be happy that your two co-owners had a bong to use. Those who didnt chip in and think they deserve to use it could possibly be the real aholes.
What did you learn in life today? SHARING ? Mmmmm what a concept.(possibly is not scientific evidence)
