Dear host family,
I still remember when I wrote my application for my exchange year. In that application, I was asked to write a letter to my future host family. I had no idea what you guys were going to look like, be like, or what your names were. When I did find out who you were, I was very excited. I still remember that day, I got the phone call. I had no idea how important you were going to become to me.
I usually have a hard time saying this to people, but it is easy to say to you: I love you. I love you guys with all my heart. I am more than grateful, that you guys decided to let me into your home, your lives and your hearts.
Saying goodbye to you is the hardest thing, but I hope we will stay in touch forever.
