Grammar: Awake

John e-mailed his friend, but his friend did not respond. 'He hasn't awoken yet,' John realized. It was already 6:30, so he called his friend's house to wake him up.

John's friend answered in a drowsy voice. 'I thought maybe you haven't gotten up yet, so I called to wake you.'

'Thanks,' said his friend. They went to school together and studied some more for the test.
