When it is time for the swallow to migrate for the winter, her good friend, the turtle, is afraid of forgetting her even though she promises to return, no matter what she suggests could serve as a reminder.

A little girl catches a cold from her seatmate at school, chickenpox from her little brother, and other illnesses from other people, but there is one contagion she really does want to catch.
