Write fiction inspired by a public sign

Use the harmless phrase on this public sign, [SIGN PHRASE], as inspiration for three original micro-stories in different genres: quiet comedy, gentle mystery and hopeful speculative fiction. Each story must be 120–150 words, have one concrete location, one character choice and an ending that changes how the sign is read. Do not copy a named author's style or imply that a real person on the sign performed an action. After the stories, give a one-line explanation of the different narrative mechanism in each. Avoid overused 'it was all a dream' endings and excessive exposition.
