You need to ask a question. Never apologize for needing more information. Instead, just ask it.
You need to voice a negative opinion. As long as you do it with tact, you should share your feedback, especially when it will prevent the team from making a bad decision. Don’t preface comments with “I’m sorry, but …” Instead, say “Here are my concerns …, and this is how I think we can improve the idea/plan.”
Someone asks you to clarify a point. You may not be to blame, so don’t blurt out “I’m sorry I confused you.” Instead, say: “Sure …” and then repeat your statements.
You show up late. No need to offer up a litany of excuses. Just dive into the topic with: “Thank you for being so patient. I know your time is precious, so let’s get started.”
