The phrase "little piece" is an idiomatic expression that means a small part or fragment. It can be used in various contexts to describe something that is not complete, but rather just a portion of it. For example, if someone says they need a little peace and quiet after a long day at work, they mean they want some time alone to relax and unwind, without any distractions or interruptions. In another context, if someone refers to their car as "my little piece," they are indicating that it is not a fancy or expensive vehicle, but rather just something that gets them from point A to point B.
