Can someone help me on writing a personal narrative or a story-illustrating an event or experience exemplifying gratitude. In other words, I need to share a colorful story about an experience or event for which–either during or after the event– I feel or felt thankful?

I need to have a beginning, middle, and end. Story will be written with a clear introduction paragraph, a body of story-development paragraphs, and a concluding paragraph. Has to have a clear thesis statement.
