The Sandbox tree is not a friend because only those who do not know it fall in love with its alluring shade. If this is not the tree about whom it was said; "...for in the day that thou eatest thereof thou shalt surely die."
The Sandbox tree has worked hard, using its defensive mechanism to meet the description of the tree in Genesis. Though it may not be the actual genesis tree, it is only best to keep a safe distance from the Sandbox tree.
