There are many topics considered taboo in the cultural sphere, including death, grief, jealousy, forbidden love, and lust, to name a few. The Unsent Letter Mailbox is a temporary public installation and live storytelling event where "spectators" are invited to write an unsent letter and, in exchange, read one written by someone else. Providing anonymity to participants protects their identities and creates a safe environment for them to express their thoughts. This practice offers a cathartic experience for both writers and readers who may see their own emotions reflected in the unspoken words of others.

The Unsent Letter mailbox project invites New Yorkers to address their unsent letters to a moral void. What we decide to share and keep private depends on the moral constructs we interact with — what is socially acceptable and what is not?
