guilt

a few days ago i saw a group of kids my age or younger smoking near the railway track.
i was on my way to math tuition and so i just looked at them , shocked, but i didn't ask them to stop or anything
a girl was with them, the only one not wearing a school uniform, and she looked pretty sick
 maybe it was her first time smoking.
and i didn;t stop and help.
i was appalled that kids my age could be smoking, instead of having a happy childhood.
