premise: a skater grinding down a rail in front of a latin store while three onlookers watch. hypothesis: A skater in neon green shorts is doing a trick on a rail in front of 3 girls he is trying to impress.
neutral: The skater is never described so we don't know has neon green shorts. Grinding does not entail a trick, but simply sliding down the rail. The onlookers are never defined as male or female so we can't know they are 3 girls. The skater's motive is never established so we can't know he is trying to impress anyone.
