" Do you know what I like about your program? Even when I’m running the vacuum, I can understand it. "
- Thelma Ritter

When someone praises a program by saying they can comprehend it even while performing tasks like vacuuming, it means that the program's design is intuitive and user-friendly. It suggests that despite being engaged in another activity, which typically requires attention and focus, the individual can still easily understand and interact with the software.

This quote delves into the broader concept of usability and simplicity in technology. The speaker appreciates a program that doesn't demand excessive mental effort or require users to pause their current activities to figure out how it works. This kind of user-centric design reflects an understanding that people's time is valuable and that interruptions can be disruptive. A program that allows for seamless integration into daily life, making efficient use of spare moments, enhances the overall user experience significantly. It underscores the importance of designing technology that complements rather than distracts from our daily activities.

The quote is attributed to Thelma Ritter, an American actress known for her roles in classic films and television shows during the mid-20th century. Her work often involved bringing depth and charm to supporting roles, making her contributions memorable and beloved by audiences.
