The line "well women are used to worrying over trifles" is a reference to the idea that women are traditionally expected to focus on small, insignificant details or "trifles" in their daily lives. This line is often used to express the idea that women are overly concerned with small things and that they lack the ability to see the bigger picture. The line is often used in literature and popular culture to portray women as being overly emotional, irrational and domestic.
The significance of this line can also be seen in a more critical sense as it perpetuates a stereotype about women and their supposed tendency to focus on small, unimportant details. It can also be seen as an expression of the societal expectation that women should prioritize domestic matters and neglect more important issues.
This line is from the play "Trifles" written by Susan Glaspell in 1916 which is a feminist play that explores the theme of gender roles and how society views the actions and thoughts of women. The play is a commentary on how women are often dismissed and not taken seriously, and how their concerns are considered as trifles by men.
