premise: A man wipes the outside of a window clean as a girl cleans the same window from the inside. hypothesis: A family tidies up the house on a sunny day.
neutral: There is no indication that the man and the girl are related in any way, as being in a family. Tidying up the house implies things more than just cleaning windows, such as picking things up. There is no indication as to what is going on outside, that it's a sunny day.
