All the bugs in my software that others run into have the following story template:

• t = n: my program was responsible for x and y
• t = nn: my program became responsible for x, y and z
• t = nnnnnn: bug in z (interacting with x/y)

Adding z required rethinking the entire program. I tried to patch it in. Implications were not fully worked out.
