My sister and brother-in-law came to my house for the first time after marriage and asked me to propose a toast. I don't know what to say after getting up. I didn't say yes. It's a little embarrassing. They always treat me like a big boy. Relax. Relax. Say less if you are afraid of saying the wrong thing. If you're afraid of being told you won't talk. You should let more food (for example, give your sister more food) and care about chatting, for example, about your sister and children (praise them as much as possible). The governor is polite. Remember one thing: don't sulk, keep smiling. This will help you to enter the society in the future.
