Systematic

At work I see the same students,
at the same time,
on the same day of the week.
Sometimes for years.

I usually do my laundry on the weekends, so I start the week with all clean clothes.

I have my favourite shirts, and unconsciously wear them in the same order everyday of the week.

Some of my students have probably seen me wear the same shirt every week for months on end.

I can't wait for warmer weather, so I can start wearing my 5 t-shirts!

Teeth

In Japan there is no Tooth Fairy.
The upper teeth are thrown on the ground outside the family home.
The lower teeth are thrown up on to the roof.

No one has given me a reasonable explanation for this.

To be fair, I've only asked 6 year olds so far.

Misinterpretation

When I was in La Paz, Bolivia I shared a room with a Dutch guy for a few days.
One day he came back from wandering the city and said that he had walked by a whole area filled with brothels and sex shops.
The next day he showed me the area.

They were all unisex hair salons.

We were both disappointed.
