Why do american put marshmallows on sweet potatoes

It’s a tradition, most people do it for thanksgiving or big family gatherings.

This is an opinion question. I would like for someone to believe in me because when you are going through a hard time it's nice to have someone who stands by you and believes in you and is supportive rather than someone who is tearing you down. Yet it is also important to stand by your beliefs and if you do not have someone like that but you believe that is what you want to do than you should do what you want to do.
