Nicholas, for yourself one of these days, if you ever fall in love with anybody, as I trust and hope you will, provided she is respectable and well-conducted, and of course you'd never dream of falling in love with anybody who was not), I say, I can assure you that a great deal more depends upon these little things than you would suppose possible. If your poor papa was alive, he would tell you how much depended upon the parties being left alone. Of course you are not to go out of the room as if you meant it and did it on purpose, but as if it was quite an accident, and to come back again in the same way. If you cough in the passage before you open the door, or whistle carelessly, or hum a tune, or something of that sort, to let them know you're coming, it's always better; because of course, though it's not only natural, but perfectly correct and proper under the circumstances, still it is very confusing if you interrupt young people when they are—when they are sitting on the sofa, and—and all that sort of thing, which is very nonsensical perhaps, but still they will do it."
The profound astonishment with which her son regarded her during this long address, gradually increasing as it approached its climax, in no way discomposed Mrs. Nickleby, but rather exalted her opinion of her own cleverness; therefore, merely stopping to remark, with much complacency, that she had fully expected him to be surprised, she entered upon a vast quantity of circumstantial evidence of a particularly incoherent and perplexing kind, the upshot of which was to establish, beyond the possibility of doubt, that Mr. Frank Cheeryble had fallen desperately in love with Kate.
"With whom?" cried Nicholas.
Mrs. Nickleby repeated, with Kate.
"What! our Kate—my sister!"
"Lord, Nicholas!" returned Mrs. Nickleby, "whose Kate should it be, if not ours; or what should I care about it, or take any interest in it for, if it was anybody but your sister?"
"Dear mother," said Nicholas, "surely it can't be."
"Very good, my dear," replied Mrs. Nickleby, with great confidence. "Wait, and see."
Nicholas had never, until that moment, bestowed one thought upon the remote possibility of such an occurrence as that which was now communicated to him; for, besides that he had been much from home of late and closely occupied with other matters, his own jealous fears had prompted the suspicion that some secret interest in Madeline, akin to that which he felt himself, occasioned those visits of Frank Cheeryble which had recently become so frequent. Even now, although he knew that the observation of an anxious mother was much more likely to be correct in such a case than his own, and although she reminded him of many little circumstances which, taken together, were certainly susceptible of the construction she triumphantly put upon them, he was not quite convinced but that they arose from mere good-natured thoughtless gallantry, which would have dictated the same conduct towards any other girl who was young and pleasing—at all events, he hoped so, and therefore tried to believe it.
