[Rain Man]

Because I have an apartment attached to my house, I have to go through every credit card transaction, electronic payment, and written check to see what expenses apply to the house, to the apartment, or to an apportioned combination of the two. It's roughly 1,200 transactions this year.

Now, you may ask if I could do it as I go and not have to do it all at once at the end of the year, and the answer to that question is yes. Yes, I could, and every year I think I should, and then I don't.
