Who's the grownup?

A park in Dulwich Hill - Australia Day 2008.

A small 7 month old baby cuts a solemn and lonely figure sitting in her stroller in a childrens playground. She stares across the asphalt to two adults in the middle distance. The pair are in their mid to late 30's, one male and one female who are busy spinning around like complete fools on a roundabout and killing themselves laughing.
