This issue of pronoun is really fascinating and interesting. In my African native language there is no he or she. We only have they. And further the language is only spoken and not written. But in English this issue is really a hot button issue.
Funny, in my language, every noun has a gender associated with it -- it is either male, female, or neutral. And then the rest of the words we use around the nouns have to be inflected to reflect that gender. All I can say is that America would go effing NUTS if this concept was in the English language!!!
