When Dell was a kid, her sister was badly injured in an accident.  As her sister was being rushed to the hospital, a stranger stepped in to comfort Dell, a gesture she's never forgotten. 

Do you have your own story of an unsung hero? We'd love to hear it! Record a voice memo and email it to us at [email protected]. 

Some guidance:

-- Focus on ONE moment that you will never forget. 

-- Make sure you're in a quiet, non-echoey room.

-- Speak conversationally, like you're talking to a friend (and please avoid reading from notes.)

-- Let us know how this person continues to impact your life.

-- If your hero were standing front of you today, what would you say? Address them directly.

-- Here are some tips on how to make a great recording on your phone.

Thank you!
