Ruby has to cross the lonely footbridge daily on her way to school. She goes and returns with friends, and still mother never forgets to remind her strictly to never pass the bridge alone. Though their colony is very safe, security guards are posted everywhere.
Ruby wonders why mother is so scared. She asks mother.
Mother looks in her eyes. She is so young and innocent; she will not understand it now.
Once mother made a mistake of crossing a footbridge all alone when she was young.
Mother still shivers.
Time heals all wounds but some scars never fade away.
