premise: Person in white shirt and blue jeans, holding hand out with an empty cup in the other, and a liquid mess on the ground. hypothesis: A guy in jeans and a t-shirt spilled his milkshake and stares horrified, holding the empty paper cup.
neutral: The person might be a guy or a gal and also doesn't have to be wearing a t-shirt; in addition, the liquid mess could be any kind of drink and it doesn't necessarily mean that he (or she) spilled his milkshake; moreover, he may not necessarily be horrified by the events, but could be amused or unconcerned by what's happened. .
