This letter here is an invitation to----, well, I shan't tell you what it is, but it's far from being a practical joke, I can assure you." Grace looked doubtfully at Elfreda, who stood very erect, her head held high with offended dignity.

Perhaps, after all, she had been too hasty.
Perhaps the two sophomores really intended playing some harmless trick.
Then the words, "We are not going to bother with J.Elfreda much longer," returned with a force that left Grace no longer in uncertainty.
"Elfreda," she said earnestly, "I wish you would listen to me for once.
Miss Wicks and Miss Hampton are not your friends.

If you accept their invitation for Friday night you will be sorry.

Take my advice, and steer clear of them." "Please mind your own business and get out of my room," commanded Elfreda fiercely.
Casting one steady, reproachful look at the angry girl, Grace left the room in silence.

Once outside her own door she clenched her hands and fought back her rising emotion.
