Mrs. Kirby came smilingly forward to greet Millicent when her eyes fell upon Worth . `` Why ! why ! '' she said . `` I did n't know you had a twin sister , Miss Moore . '' `` Neither I have , '' said Millicent , laughing nervously . `` This is my chum , Worth Gordon , but she is no relation whatever . '' At the mention of Worth 's name , Mr. Kirby started slightly , but nobody noticed it . Millicent went on in a trembling voice . `` We 've come up to confess something , Mrs. Kirby . I 'm sure you 'll think it dreadful , but we did n't mean any harm . We just did n't realize , until afterwards . '' Then Millicent , with burning cheeks , told the whole story and asked to be forgiven . `` I , too , must apologize , '' said Worth , when Millicent had finished . `` Can you pardon me , Mrs. Kirby ? '' Mrs. Kirby had listened in amazed silence , but now she laughed . `` Certainly , '' she said kindly . `` I do n't suppose it was altogether right for you girls to play such a trick on anybody . But I can make allowances for schoolgirl pranks . I was a school girl once myself , and far from a model one .
You have atoned XXXXX your mistake by coming so frankly and confessing , and now we 'll forget all about it .
