In my language, Indonesian, we don't use he or she. We only use one word, dia, but we know what we are talking about in the conversations. Now, in English language I have to use "He" or "She". But sometimes I called "she" to a male in a conversation or "he" to a female without realizing it.
I caught it sometimes and I changed it right away. I got embarrassed too sometimes. Now, How to change that habit? Help please!
