Do While Loop

This is basically how a do-while loop works in real life. First message: "I will be there in 5 minutes" (the initial statement that runs once). Second message: "If you don't?" (the condition check). Third message: "Re-read the message" (repeat the loop body). The beauty here is that unlike a while loop that checks conditions first, a do-while executes at least once before checking if it should continue—just like that promise to arrive in 5 minutes that inevitably turns into an infinite loop of excuses. The eternal programmer's time estimation paradox, but in relationship form!
