person A: I have been having a lot of money trouble and just yesterday an anonymous cashiers check came in the mail for $5000!
person B: Wow that's super lucky! So you have no idea where it came from?
person A: I have no idea_comma_ but it came at just the right time.  I was about to get evicted and my power had already been shut off.  I think it was from someone in my church.
person B: That's a true blessing. I am very happy for you!
