Here is a 7 sentence paragraph defining friendship: A friend is someone you can trust and rely on. They are there for you during both good and bad times. My best friend Sarah and I have been friends since elementary school. I remember we used to play together every day after class and tell each other everything. She was always so supportive and caring. Even now as adults, though we don't see each other as much, I know she will always be there if I need her. True friendship is built on loyalty, trust and unconditional support, and that is what Sarah has shown me all these years.

enough to include all members of the term
you are defining but no larger. Avoid adding
personal details to definitions.
