3, the endorsement type in the seat, I don't know if I can't hear my own voice or feel very quiet, but very energetic. Endorsement should not be in a quiet place like the library, but in the hall or corridor. Don't endorse in the library, you can't help but make a noise.
4. Take a bite. You said it would be okay to eat in the library. I really can't stand the squeaky sound (I have met people who can even drink yogurt, I don't understand.
5, couples are tired, then love to say that you can go out and find a tea shop to sit and chat? And really pay attention to your behavior in public, which is really speechless.
