Heyy! Hope this helps. Remember, if “and” joins two list items, don’t use a comma.

1: “He walked all the way home and he took the long way.”
2: “They gave us coffee, cheese and grapes.”
3: “Jill, my sister, shut the door behind us.”
4: “It would be helpful if you went with us, Sarah suggested.”
5: “I really wanted cereal this morning but I didn’t have any milk.
