I think it's incredibly funny now that I know the witch destroyed herself. "The best laid plans of mice and men often go awry." But, Mousie, thou art no thy lane [you aren't alone]  In proving foresight may be vain:  The best laid schemes o' mice an' men  Gang aft a-gley, [often go awry]  An' lea'e us nought but grief an' pain,  For promised joy.
