I guess your sister doesn't understand how much you care about your books. May I ask if she's very young?

I wouldn't be lending my sister anything any time soon until she learns to have some respect not only for the possessions of others, but for the effort you put into annotating that book, which isn't as easy to replace as just buying a new copy.

Discussion is the goal

Do not post shallow content. All posts must be directly book related, informative, and discussion focused.

That's so inconsiderate. I would be angry too.

What does low key means?

I’m on your side but I sometimes spill a little bit of coffee on my books because I love damaging them. I do my best to beat the hell out of them during my read. Abuse is my love language I guess haha
