Rude Teenager

I was boarding at LRT from Choa Chu Kang, saw one lady with her few shopping bags.
She walked in, and wanted to sit the nearby seating place. One boy walked so fast, overtake her, and sit on the place that the lady was going to sit.
Instead of giving the seat to the lady but the boy was staring at her.
How rude is that! sigh...

To all teenager out there, please do not do that!
