People need to know whether you are offering a suggestion or giving an instruction.

Seniority makes musings sound like orders. A thought said out loud by the person in charge gets treated as a decision, and then work happens that nobody wanted, because no one could tell which register you were speaking in. The same sentence from a peer would have been a conversation; from you it became a task.

Label it as you say it. Say this is just a thought, do what you think, or say this one I do want done. Both are useful; the confusion is what costs. And if you are on the receiving end, it is always fair to ask whether that was a preference or a decision.
