The best advice I could give Delrita is to reach out to Avanelle (repeatedly if necessary) to explain how and why her letter (Avanelle's) ended up in the wrong hands. Delrita did not purposely hand over the math book, it was maliciously knocked out of her hands.... it might make time to regain both Avanelle's trust and friendship, but Delrita needs to give her the necessary time and a sincere apology.
