Good fellows

When you write Japanese vertically,
you have to write the long-vowel line vertically as well.

I see many mistakes like this in Singapore.

On the way home today,
an auntie sat down next to me in a train and took a hook out from her bag, and she hung the hook on a handrail and hung her bag on it..!

This whole process was done quickly and really smoothly, so I guess she always does this.

Where is the borderline between her house and the public?
