Rosita and Telly want to play a game of tag but they can't find anyone to play with them. They meet Bob's niece Samara and wonder if she would like to play. She can't hear them because she is deaf. Rosita and Telly are concerned because they don't know how they will be able to all speak and play together. Samara explains that even though she can't hear them, she can talk to them by using sign language. They have a lot of fun learning, playing, and also signing and saying the alphabet together. Everyone on Sesame Street gets so excited about sign language that they all can't wait to learn more.
