That's what I thought

I was working in Cambodia for an NGO. My superior was a young, easy-going Khmer man with whom I had a great relationship. One day, I went to check some information with him, and when I received the answer I expected, I said "Ok, that's what I thought."

For me, this was an expression to show that I had thought about the question myself but out of caution wanted to confirm my response, and that I was in agreement with his decision. However, he took the "Ok, that's what I thought" to mean something like "I already knew that, your contribution is worthless." Moreover, another Khmer coworker present confirmed that she'd have taken the same meaning from it as my boss did.

I appreciated my Khmer coworkers for having the courage to explain to me something that I was doing to make them uncomfortable. They were generally pretty easygoing regarding cultural differences between the team members of different nationalities, so I believe this was something that was particularly important to them, as it motivated them to speak up.
