When someone asks you to evaluate an opinion she has, or an item she made, it’s very tempting to bla out your ideas, but it’s very important not to do so.
Take a pause. Do you really understand what she’s talking about? Do you know the intention behind the opinion or the item-making? Without knowing enough info about that, don’t rush to give out your ideas, because it can be obtrusive.
Ask questions. Have a conversation. Once you learn more about what the other person is thinking, you’ll have plenty of opportunities to talk about yours, and in a well thought-out way.
