Today I mowed the lawn for my parents.
I know this made a difference because if I hadn't done it the grass would still be long and my parents thanked me.
I felt really amped because I did my good deed and I used some of my energy up.
If my sister was involved she too would have been happy because she doesn't like doing gymnastics and stuff on the lawn when it's long since she can't see her rabbits droppings.
