I sold all my books one day and asked him to do the same with his, 'cause we were low on cash.
I spent the cash on absolute bullsh*t anyway.
A month later (today), I buy ONE of the books we sold from the place we sold it to, back.
I give you the book, and you thank me with this super-happy look on your face.
Um... IT WAS YOURS ANYWAY. All I did was give you back what was YOURS, which you gave away for MY benefit.
Now I feel guilty because you were happy. Thanks. Thanks for the confusion. ._. Stop reacting weirdly, dammit!
