I like the name Marty, and I wouldn't change it either.
Thank you for the fun read! It was humorous in so many spots -- I apologize if I peppered your story with my highlighting. I think you have a great way of telling stories, and I look forward to reading more!
One suggestion: I noticed you included a subtitle below your title. If you want to format it: highlight the text, and a pop-up menu will show. On that menu, select the smaller "T" to format your line into a subtitle.
Fantastic story, and Thank you for sharing!
