premise: A young man flips up a welders' mask as a young girl looks on, a six-pack, barbecue, and chalk message in the background. hypothesis: A welder at work notice a cute blonde girl walking past as he tries to show off his six-pack and barbecue.
neutral: Not all men in welders masks are welders and he is not necessarily at work. There is no mention of the girl being cute or blond and we do not know that the welder has a six-pack or that the barbecue belongs to him.
