Answer:
Stick to what you know
Step-by-step explanation:
I can't give 3 poems but I can give advice:
Write what you know about veterans. Maybe use how you feel about them, or what they are to you. For something funny, it doesnt have to be a joke, it could just be silly. For what if, think about one of the things you have thought about. Like a crazy idea or an odd situation.
I hope this helps.
