In the play "Trifles," Glaspell describes how men can ofetn dismiss women's concerns and opinions, or overlook important factors because they consider them not worth their time.
In this feminist play, several investigators fail to solve a crime because of their prejudice. Thinking that certain "female" things are unimportant, they fail to notice certain clues that matter.
An example of this occurs when they see the cans that "exploded" in the kitchen. While they think this is unimportant, the cans point towards the frustration that Minnie felt in her life. Another example is the old, ugly clothes that Minnie wore. This shows that her husband restricted her money severely. Finally, the women notice that the quilt Minnie was making was sewn badly and carelessly towards the end, which shows how upset she must have been. However, the men think that this is a pointless thing to consider.
