二哥给大双的信：

亲爱的大双，

如果你接到这封信，那就说明我们成功的和未来的对接，时空的连续性已经改变了！也就是说，当你回到家时，你回到的不是你以前住过的那个家，而是在不同的时空的一个新家了！

也许你看起来家里的东西都一样，但是我们已经跨越到了未来的时段。你不会是原来的你了，这次出游，通过做一个好朋友，好哥哥，好同学的磨练，你会带着一个崭新的面貌出现在我们面前，因为我对你有充分的信心！

另外我想说，你对钢琴的认真，执着让我印象太深刻了。尽管有时我觉得你弹琴的声音有点太大了，对你翻过白眼，但你对自己应该做的事情认真负责的态度，让我绝对相信，你将来一定比我强！

想念你和小双，等着听你讲你们讲淘金的故事，照顾好自己和小双啊！

爱你的二哥。

另外，给你出个谜语：如果你拥有它，你就很想分享。但你一分享，就不再拥有了，这个东西是什么？（谜底在小双那）

另外我想说，很高兴你最近对篮球着迷了，你勇敢的迈出了自己的舒服区去挑战新的事物，很棒！和你说实话吧，你现在可比我那个时候的的体育要强两倍，（我在你那个年龄时，可是个矮胖子）。你会很快的成长为一个很有特色的人的！

想念你和大双，等着听你讲你们讲淘金的故事，照顾好自己和大双啊！

爱你的二哥。

另外给你出个谜语：一个东西，有一个面孔和两只手，但没有身体，这个东西是什么？（谜底在大双那）

Dear Jason,

If you are getting this letter then that means our mission to the future has been a success and the time space continuum has been altered. This means that when you get home, you will be arriving not to the home that you once knew but to a brand new home located in a different time period. Everything will look the same, but do not be deceived. You see, everything has moved into the future by a vast … few days. You will come home an entirely different person. That is because I am confident that you have grown tremendously as a friend, brother, and classmate during this field trip.

On another topic, I just want to say that I am so impressed with your constant diligence with piano (even when sometimes I give you glares for playing too loudly). You are so dedicated and responsible about what you do. I have no doubt that you are going to be a much better person that I ever was.

I miss you and can’t wait to hear all about your stories in gold country. Take good care of your brother.

Love,

~Will

PS: If you have it, you want to share it. If you share it, you don't have it. What is it? Ask Joseph for hints if you need them.

On another topic, I’m really glad that you’ve picked up a passion for basketball recently :) I can see that you’ve really gone out of our comfort zone and you are already twice as athletic as I ever was (trust me, I was pretty pudgy). You’re growing up quickly into a someone with great character.

I miss you and can’t wait to hear all about your stories in gold country. Take good care of your brother.

Love,

~Will
