I assume everyone thinks like me and am genuinely surprised when this is not the case. "You'll like it." "How do you know I'll like it?" "Because I like it, so how could you not like it?"
I ran into an aquaintance yesterday whom I had not seen since running into her at a movie theater about a few months ago. She asked if I enjoyed the movie we'd both seen, I said yes and asked if she'd seen another one I'd liked and she said no, but her friend saw it and nearly walked out because of how bad it was. (bad = poorly written) I said, "Are you KIDDING ME?! It's hilarious! It's great! She's crazy!"
