Some people have been taught that 'will' is 'the future' in English. This is not correct. Sometimes when we talk about the future we cannot use 'will'. Sometimes when we use 'will' we are not talking about the future.
We can use 'will' to talk about future events we believe to be certain.
Often we add 'perhaps', 'maybe', 'probably', 'possibly' to make the belief less certain.
We often use 'will' with 'I think' or 'I hope'.
We use 'will' at the moment we make a new decision or plan. The thought has just come into our head.
