Waiting for the School Bus

What are these cute kids doing? Waiting for the school bus after a hard afternoon of play (like all the dirt on Desert Girl's clothes?)

 They have a very good reason to cover their ears--the air brakes on the bus! It's something most of us wouldn't notice, but their delicate little ears realize that that noise is quite loud. They also think it's kind of funny to put their hands over their ears.

 The school doors open, and off comes big sister Ava.

Then comes big brother Desert Boy (in a slightly grumpy mood). Maybe a trip to the playground is what everyone needs!
