don't trouble trouble till trouble troubles you

proverb If you think something could be problematic or dangerous, then don't do something that might provoke or instigate it. A: "That dog looks like it could be mean. We should go scare it off." B: "No way, leave it alone! Don't trouble trouble till trouble troubles you!" A: "I accidentally scratched his car pulling out of the parking lot last night. Should I offer to pay for it?" B: "No, he might not even notice. Even if he does, he wouldn't know who did it. Don't trouble trouble till trouble troubles you." Don't trouble trouble till trouble troubles you—just wait and see how she treats you at the birthday party.
