Miscalculated...

I thought that it would be cheaper to travel by train, that's why I insisted on parking at the KTM station. We had to go to her sister's place and I decided to go by train to cut cost. However, it proved to be a wrong decision.

I'm sorry that you were sandwitched in between strangers.
I apologize for only thinking about saving cost.
I will never have you go through the same situation again.
Sorry.
