If you receive an e-mail and it requires you to take action, read the e-mail in its entirety for understanding. Then, if you have questions, read it a second time. If you’re still not getting it (and there is nothing wrong with not getting something), then you ask. But if it is evident that you skimmed an e-mail and then reach out to me for clarification, I will reply to your e-mail by forwarding the initial e-mail with the words “See highlighted,” and highlight the part you failed to read thoroughly the first two times.
Sorry, not sorry.
Make common sense a priority.
