It was on a reserved-seat train
It was lunch time so many people were eating their lunch on the train. The two women behind me started talking. I don't think they were traveling together. They looked middle aged and taked quite loudly.
When they found out that they both had a pet dog they sounded so happy to talk about something they had in common. One of them talked about when her dog got sick and how she found out.
"His output looked strange so I decided to take him to a vet and I was right." Then she said how the "output" looked and how it smelled and so on in great detail.
I couldn't help it - I told her not to talk so loudly about something like that as we were having lunch. One of them got upset and told me, "You must know that pet and baby output are not something dirty."
There was a man sitting on the other side of the aisle from these women. He said "It is dirty!" Then she said, "You don't know anything about babies and pets because you are a man! You have no delicacy!"
The other woman said "I'm sorry, we shouldn't have talked about our pets' output when you were having your lunch." Then the other one got upset with her and said "You don't need to apologize, they are all wrong, not us!"
Suddenly, She found that everyone around her looked upset and she said "I don't want to stay here with people who have no love for animals!" She then left her seat and didn't come back.
