occam's razor
A rule that tells you to pick the simple answer, not the messy one. Don’t add extra nonsense unless it’s actually needed.
Your ex sent you a message. It didn’t mean they love you back. They just felt bad.
Your neighbor’s cat is on your roof. It didn’t mean the cat is plotting against you. It just wanted to nap.
Your mom called you. It didn’t mean the end of the world. It just meant she wanted to chat.
