Dear Sarah,
The days are becoming limited, and I am getting quite nervous. I know you will take care of Zachary, but I just need you to know a few things as you embark on this new journey with my brother. Zack is fragile. Although 99.9% of the time he is being goofy, that doesn't mean that he doesn't truly care. Be careful what you say, and acknowledge his feelings. Sometimes he acts the way he does as a front, so be cautious when you are speaking about your feelings and be sincere when he talks about his.
Please don't take advantage of him. He has such a big heart, and that can easily be hurt. He would give the shirt off of his back to anyone and I promise that not everyone is willing to do the same in return. He is easily persuaded, but again, do not take advantage of his willingness to give to others.
He is goofy, yes, so sometimes you have to bite your tongue. Do you know how many times I had to bite my tongue or pretend like what he said didn't hurt my feelings? Not too many times because he is so cautious of others and he would never want to hurt anyone. When he is being a pain in the butt, confront him, but don't yell. Zack is always up for suggestions and he likes to make room for improvement, especially for you. Approach him respectfully, and he will do the same to you.
Go on adventures with him. He loves the outdoors and he loves to explore. When he is ready for an adventure, he will let you know and please join him on this journey. I always used to be the one exploring the world, and taking on challenges with him, but now it is your turn and let me tell you something, you are one lucky girl!
I know that this experience can be scary, but just remember, love can be scary. But love conquers all, and you and my brother have nothing to be afraid of. You will continue on this path with each other for eternity. Be sure to love and support each other throughout this journey. Frequently say I love you, and never go to bed fighting. Always give each other a kiss before you leave for your day, and never hold a grudge.
Take care of him for me, and know that every day is a blessing.
Love always,
Your new sister
