I have one idea of skitt one can be father and other son

there was a boy named a 
 a get stick chewing gum on his leg that was thrown by someone .
a - oh! see today's people litter here and there . see that gum i will through it at bench 
[ a throw it on bench]
after playing they went back to home a see that the gum was not there
a - now it's good [ when he goes back to home]
a's father - is something on my back . everyone was laughing at me in park
[ a sees the gum he had thrown and feel guilty and ashamed]
now he decided to never litter
