In my grammar book I have the following:
Jack has gone away. He will be away until Wednesday.
The first sentence is Present Perfect but the second one is Future Simple. Could you tell me why we don't use Present tense in that context?
Jack has gone away. He is away until Wednesday.
Is it possible to use Present here, or because of "until Wednesday" must we use Future Simple? So, we can say "He is away." "He is away now." But can we say "He is away until Wednesday." if he has already gone away?
