Lords Of The Flies
At kindy there are, thankfully, a troupe of 4 year olds guys equally as rambunctious as Cal. They're all highly verbal, highly adventurous, highly energetic, highly hard to wrangle. Cal is the youngest of them and loves to follow them on imaginative adventures through the bush next to kindy every afternoon.
There's a hidden dirt trail that slopes down the side of a robust date palm that they've named 'The Dinosaur Hole'. And a steep, dense bushy path to bowl balls down and then run after. The balls mostly stick to the track to be caught at the bottom, although sometimes they rocket away into the thick scrub never to be seen again.
