Toothbrush

This was taken in the park where the trees are generally left alone, giving it a semi-natural look. Until you look closer around the base of the tree. 
Did it just fall from the sky or did someone deliberately bring a toothbrush to the park to throw it away.  I suppose the toothbrush could have been dropped accidentally, but that means someone set off to go to the park with their toothbrush. 
Odd behaviour from any of the scenarios.
