But I had another engagement for that afternoon , so could n't go . Mr. Kirby is a business friend of Dad 's , and they are very nice people . The other invitation is to the annual autumn picnic of the Alpha Gammas . Now , Worth Gordon , I simply must go to that . I would n't miss it for anything . But I do n't want to offend Mrs. Kirby , and I 'm afraid I shall if I plead another engagement a second time . Mother will be fearfully annoyed at me in that case . Dear me , I wish there were two of me , one to go to the Alpha Gammas and one to Beechwood -- Worth Gordon ! '' `` What 's the matter ? '' `` There are two of me ! What 's the use of a double if not for a quandary like this ! Worth , you must go to tea at Beechwood Saturday afternoon in my place . They 'll think you are my very self . They 'll never know the difference . Go and keep my place warm for me , there 's a dear . '' `` Impossible , '' cried Worth . `` I 'd never dare ! They 'd know there was something wrong . '' `` They would n't -- they could n't . None of the Kirbys have ever seen me except Mrs. Kirby , and she only for a few minutes one evening at dusk .
They do n't XXXXX I have a double and they ca n't possibly suspect .
