Why do we do this? follows a year-long relationship with checkpoints at four specific months along the way. Each month is represented by an envelope. Inside each envelope is a card. On the front side of the card is a statement about how the girl feels about the relationship at that time and on the back is a statement from the guy. I asked a female and male student in the class to handwrite the statements, to give the piece more of an actual voice. This book, both funny and sad, is an objective look at relationships and questions why we always find ourselves in these situations.
