Imagine a small town or village by the water, (lake, ocean, river). Go into the town or village and find a person or family and write a poem about what goes on in their life today.
Since it's Mother's Day, a poem about mothers seems appropriate. You don't have to write about your mother, it could be motherhood in general or your being a mother, it could you know a real motherf*****r, or something that is the mother of all something.
