A few weeks later Kirsten handed me the _______ dated Aug. 30, 2002. Around then I was preparing for my pilot course’s final exam at the _______ school. The students finished the training on _______ days.

I was the first to _______. My mother’s letter _______ after I left. Kirsten picked it up from my mail-box, to keep _______ she next saw me. _______, a few days later, when it was her turn to leave, she ________ the letter among the piles of papers she ________ packed into boxes. It ________ there for a decade, during which my mother died. In 2013, when Kirsten ________ some dusty belongings from her flying school days, she ________ the letter.

It’s been two years since Kirsten gave me the letter which I’ve carried on my long flights. But I haven’t ________ it yet. When I told some friends this, they ________ their heads. They said they wouldn’t have been able to wait a second. Of course, I ________ -How could I not? -about her ________ in the envelope. Surely, I think, she had written to wish me luck, ask about my life and tell me the news from ________ to make me at ease.
