Her answer
All this time she had worn her own engagement ring around her neck. All this time she hadn’t noticed. Anna immediately said “Yes” and kissed him passionately.

She risked losing it for two whole years!
Terry clearly had a lot of confidence in his girlfriend. She had carried the necklace with her lovingly all this time.
