I work in an admissions office at a graduate school. When we have received all of an applicant's materials and the application is complete, we send an e-mail notifying the person that the file has been completed. Sometimes people write back and say things like, "Thank you for letting me know," or "I look forward to your decision."
Anyway, someone just wrote us back saying this:
Oh my goodness! Thank you for letting me know! Wish me luck!
You're welcome! Goodluck!
