Passage: I have relatives that live very far away from where I do , and unfortunately they do n't have access to the same technologies as me , so I ca n't communicate with them over the Internet . For some time , we 've had to do it the old-fashioned way - by writing letters to each other . After enough time would pass since one of them would send me or my family a letter , I would begin to work on one . I would write for a few minutes , usually talking about things that my family recently did , and asking them how they 've been doing . If possible , I would even attach pictures to the letter , so they could see what we 've been up to . The next morning , I 'd drop it in my mailbox for the postman to pick it up and take it to the post office . Usually , they would write back within a week responding to my letter . Question: When would they close up the letter in an envelope? Option1: when the letter was done Option2: Before they finished writing it.
when the letter was done
