My daughter's art features an unusual and unexpected element

We were thrilled to find our daughter's piece of abstract art was hanging at the front of her school, in a position of great prestige. 

Then we noticed the top right corner of her piece, which appears to feature two cocktails. 

Anytime an alcoholic beverage appears on the work of a third grader, you have to wonder what is going on at home. 

It should at least give pause. 

But I almost never drink, and Elysha and I don't drink in the home or even at restaurants when our kids are with us. Clara has never seen her parents drinking cocktails. and as far as I can tell, she's ever even seen a cocktail, except she apparently has.

If so, where? And why has she placed them so prominently in her work of art?
