Argh! A professor at my uni, not my supervisor, loaned me a book recently. I was planning to give it back to him this week but accidently spilled a glass of water over it yesterday. It is still in good condition but the bottom of it is obviously water-logged. However, the damage is superficial. Do I:
a. Buy a new one, even though it costs £40, which I can't really afford at the moment
b. Come clean, offer to buy a new one in the hope that he'll say no
c. Give it back and not say anything
I'm swaying towards b. - What do you all think?
