The doors opened. A young office lady boarded the train after people have alighted.
A teenage boy in his school uniform sprung up from his seat and jumped in fromt of the lady.
"You can have the seat. Please have a seat," he said in a very loud voice while swinging his gand pointing to the seat.
The lady had a shock and moved a step away as she murmured in a trembling voice, "No thanks."
The boy then turned to face the door and mimicked the train announcement, "Doors closing."
He started talking to a man standing besides him, "I've seen you before. You working at...."
The man ignored him.
Another older lady who was standing behind him moved away.
She displayed a disgusted look and was mumbling away cursing and swearing at the boy.
It's clear that the boy was behaving differently from most people and he probably didn't know he is affecting others and couldn't control himself.
The older lady can see that yet chose to get upset over it and swear at him.
