I'm not deliberately trying to be more Vietnamese, but I've started to:
- Politely touch my left hand to my right forearm when presenting business cards or other things to a Vietnamese person.
- Look for fish sauce before tucking into any Vietnamese meal.
- Need a cup of Vietnamese green tea to round off a meal.
- Wear my slippers/flipflops everywhere.
- Ride pillion on a motorbike without holding onto anything.
