Today I was studying in the library, and the person at the next table accidentally spilled coffee on my notebook. Before I could even react, he started apologizing and said he'd buy me a new one. I said "It's okay, really, no problem," but inside I felt a little sad—that notebook had all my notes from late-night study sessions. Why do I always say "it's okay" without thinking? Sometimes I want to shout, "I actually mind."
