About 14 years ago I was walking along the street and people kept bumping into me. It was so annoying. The others on the short term team and similar experiences if my memory serves me correctly. I felt like everyone in the whole country we were visiting was being rude.
A long termer nodded knowingly when we shared our frustration. They explained that as we were from Australia, where people drive on the other side of the road, we also subconsciously walk on the other side of the road too. So all the people in our host country thought we were the ones being rude?!
I try to remember this experience when I'm feeling frustrated with things in Cambodia. Sometimes it seems people are being so rude, or various other negative things that make life hard. But I keep trying to tell myself maybe they see me as rude or lacking common sense/doing something weird/doing things the wrong way/wearing weird looking clothes/ liking ugly furniture/ thinking good things are bad/ putting value on what I see as worthless etc etc.
