So whose fault was it?

The facts:
-There was marker all over the bedspread.
-There were three markers (with and without caps) in Hokiefriend's bedroom that had originally been downstairs, accessible in a child's desk.
-The boys had been allowed free reign of the house while us mommies hung out in the living room.
-The boys had been told they were not to have crayons all over the house, due to last weeks "writing on the walls" incident.
-The boys had been told markers were for the dry erase board only.
-Hokieboy is 4years and one month old; Hokiefriend will be 4 next month.
-Hokiemama (me) is 30; Hokiefriend's Mommy is 28.

Observations:
-Markers were accessible at all times to curious preschoolers.
-The boys were never told the markers needed to stay downstairs.
-The boys were not supervised upstairs.
-The boys average 4 years old.
-The mommies average 29 years old.
-When confronted, each boy said the other one did it.

Conclusions:
-The boys probably knew they were not supposed to draw on the bed, but it cannot be determined for sure.
-The boys have impulse control issues; they are 4.
-The mommies did not draw on their additional 25 years of life experience to make some simple decisions that could have prevented the situation (ounce of prevention v. pound of cure, HELLO!)

Verdict:
-Boys: Guilty of succumbing to typical impulses affecting young children.
-Mommies: Guilty of stupidly allowing children with access to destructive materials to run amok unsupervised in a home with items that the mommies do not want destroyed.

Sentence:
-Boys: immediate suspension of coloring privileges until further notice; three strikes rule in effect: one more coloring offense and boys will not be allowed to play together indefinitely.
-Hokiemama: embarassment at seeming lack of control of Hokieboy's actions; awkwardness of not agreeing with Hokiefriend's Mommy's method of punishment; possible participation in replacement of destroyed comforter.
-Hokiefriend's Mommy: find a way to remove dry erase marker from comforter; failing stain removal, possible replacement of comforter; other ramifications unknown to this entry.

Conclusion:
Keep all markers out of reach of children unless supervised.
