The quote "Assumptions suck. They're like expectations. Assumptions and expectations will kill any relationship" from Ruth Ozeki's book "A Tale for the Time Being" highlights the importance of clear communication. It suggests that when people make assumptions or set expectations in relationships, they can create misunderstandings and disappointment. These unspoken beliefs can ultimately lead to resentment and conflict.

This idea emphasizes the need for openness and honesty in interactions with others. By avoiding assumptions and expressing our thoughts and feelings directly, we can foster healthier connections. The message serves as a reminder that to maintain strong relationships, it is essential to manage our expectations and communicate effectively, thereby preventing the pitfalls that assumptions can create.
