Maybe the cartoon boys are waiting for their favorite show to start on TV. Or perhaps they're waiting for a friend to come and play with them.
I'm not sure specifically what the 'bus boys in waiting story' is about as it's not a very common well - known story title. It could potentially be about bus boys (usually those who clear tables in a restaurant) and their experiences while waiting for something, like waiting for more work, waiting for a promotion, or waiting for a particular event to occur in their work environment.
The cartoon kid could be waiting for a special event or a gift. Sometimes, kids have all kinds of expectations and they wait patiently for them to happen.
Since I don't know the details of the story, it's hard to say for sure. But presumably, the main characters would be the bus boys themselves.
It usually implies that boys' behavior is expected to be a certain way, like being mischievous or energetic. It's a kind of stereotype.
It could mean the man is expecting something or someone. Maybe he's in a suspenseful or anticipatory situation.
The woman might have a look of anticipation, maybe standing still with her eyes fixed on something in the distance.
Well, in cartoon images of waiting, you might see characters standing with bored expressions, looking at their watches, or maybe daydreaming to pass the time.
The charm of a waiting cartoon girl could be in the way she holds hope or the emotions she shows while waiting. Maybe it's the stillness and the story that her pose implies that attracts us.
Often, the humor in waiting cartoons comes from the funny expressions and reactions of the characters. Maybe also the absurdity of the waiting scenarios. But it really depends on the specific cartoon.
The girl waiting in a cartoon could symbolize patience or anticipation. Maybe she's waiting for something important or someone special.
