The man in the hat reaches for bubbles spewing from the boy's bubble gun, to the delight of the little boy. Meanwhile, over at the right edge of the photo, it almost appears that the other little boy is drinking from his bubble gun. Surely not!
The man keeps his hand out even after all of the bubbles have floated beneath it. Looks sort of like he's saying, "Gimme five!" to the boy in the Athletics' T-shirt.
The boy squeezes the trigger and bubbles spew into the air, catching the sunlight. Meanwhile, over at the right edge of the photo, the other boy's shooting bubbles, too. In between the two boys, there is a young woman who I figure must be their big sister. She looks too young to me to be their mother. What do you think?
Ah, boys will be boys! It's a bubble shoot out! Wait! Has the man said something alarming that the young woman has overheard? I prefer to think that he said, "It's great that they brought the bubble guns with them because watching the bubbles helps me pass the time in this long, long, line."
Yes! Smiles all around as everyone continues to enjoy the bubbles. I say, "Thanks, boys!"
