I - (show) Interest in deaf people.
S - Stop what else you are doing (don't be distracted by other things, this will frustrate them).
T - Think about what Deaf people are saying (take your time to understand them).
E - Empathize with Deaf people (show that you care and that you're there to help them).
N - Notice body language (body language is very important in reading the feelings of others; Deaf people cannot hear your "tone" so instead they look at your body language).
