The three items that I would choose would be my iphone, my contact lenses and my cook book.I would explain that my iphone has music on it that I love and that may differ from another culture, it has pictures of me and my family and friends, and it has all of my contact information, important dates and even a GPS that I hope will help me find my family if separated. I bring my contact lenses because of course if my pair tear I will need a new pair to see, and my cook book because i as created by my mother and will allow me to create meal that will fulfill me in the event the food from my host country is not appetizing. I will also be able to share my favorite meals, music and memories with those from my host country.
Id be devastated if I was told I cold only keep one item, but I know Id choose the iphone as it has the most collected memories and information.
The insight that I feel I've gained from this exercise is that we love music and comfort food. Every family is different just as every culture is different. So it is important to create memories and tradition to carry on from generation to generation and share with others that differ from you.
