If there's a situation where I can speak either English or Arabic, I would choose English.
I know that I can break this sentence down to smaller and simpler sentences like "In some situations, I have the choice to speak English or Arabic. And I prefer speaking English" but I would like to use this long sentence that contains the conditional IF and the word either.
I think the rules are: "If(present), (future, will)" or "If (past), (would)". Now, I used present tense and then I feel it's better to use (would) instead of (will) but I don't know why?
