I urge fellow citizens not to jump to conclusions in their haste to prod others to do the right thing ("I was unwell, says commuter in seat spat"; Oct 31).
We may not be privy to other information to explain a person's seemingly ungracious behaviour.
To avoid possible spats over seats on the train, I carry around with me a lightweight foldable chair purchased from the pharmacy.
Whenever there are no available seats on the train, I open up the chair and sit on it. I do this without obstructing others as I deliberately choose the first or last cabin, or the space adjoining two cabins.
