The train has just left and she walked towards the bench to take a seat.
She noticed some jelly like patches on the corner she had wanted to sit and moved to the other side.
A lady in black came.
The first lady saw that the lady was about to sit on the stain but did not warn her. She just kept looking.
Luckily before she sat down, she took a look and noticed it. So she sat down a little further away.
A young guy came.
The lady in black warned him of the stain.
He thanked her and walked away.
A man came.
The same lady warned the man as well.
The first lady kept looking at what's happening.
The train came.
Both ladies boarded the train.
A young girl came and sat down on the liquid.
