10.30 sf!!!that's what I have paid to the library for my late books. grrr! and to think that I thought of buying 200 grams of chestnut for 5.60 sf. Well, I just skipped the latter just to remind myself that next time I have to be careful and check the date. This is just one my silly tactics, not only because I love chestnuts but paying that amount due to my inattentiveness made me cringe.
