Don't butterflies feel the burden of their wings? Wings they themselves can't admire. You often see children chasing these beautiful insects (if mosquitoes wasn't so keen on eliminating us, it'd have been beautiful too) with no success. They keep doing it repeatedly, hoping they'll somehow outrun their prey. They never do but they don't give up either. And then one day, all of a sudden, these kids grow up and switch on the mosquito repellants in their room. Mosquitoes aren't worth running after.
Moral: Chasing is just for the time being regardless of what age you are.
