The rule that states "before we go to sleep tonight after smoking this weed, we have to let the incesnse run out." this rule was put into effect because people were smoking and wasting weed because they fell asleep so fast.
The 12 month rule is when parents have to stop saying how many months old their baby is after they reach 1 year old. Some parents say their baby is 34 months old. They make you do extra math when they could easily say 2 years and 10 months old.
