This is true. As an immigrant myself, I have struggled with expressing my thoughts for the longest time. Different cultures and different ways of learning English. Trying to translate my thoughts from my own language to English often comes out either rude, or just wrong. I’ve learned to take moments before expressing my thoughts and then also explain just in case. I also throw in a disclaimer when I meet new people, especially at work. I’m getting better. It gets better with time. I feel bad for him. People on the internet are just brutal.
