Buying books or borrowing them?

I love buying books, but I will soon have a library of my own if I keep it up. I prefer to borrow them most of the time. I either get them online on OverDrive, with my library card, or I borrow hard copies from friends or the real library. I don’t normally reread books and I keep track of the ones I read so borrowing books hasn’t been a problem for me. But I do love strolling into a bookstore every now and then to get me some new reading material. 🙂
