Last week, my brother Tom attended a friend's birthday party, at a Stanford dorm. In the middle of singing the birthday song, his phone rang.
Tom: [stepping out into the hallway] Hello?
Our mother: [very loudly] Tom, can you hear me??
Tom: [walking down the hallway further from the party] I can hear you just fine. Can you hear me?
Mom: Hello? Hello? I'm using my desktop computer to dial to your phone! I can't hear what you're saying.
Tom: [louder] How about now?
Mom: That's better! Tom, I need your help. My laptop is showing a blue screen with weird characters, and it won't respond to any key presses! I already emailed Microsoft and they didn't reply with anything useful.
Tom: That just means the computer crashed. You need to reboot the laptop.
Mom: I pressed the power button and nothing happened.
Tom: You need to hold it down for 20 seconds.
Mom: [silence] ... Ah! There it goes! Okay, thank you. [distractedly, while typing keys on laptop] So how are you?
Tom: [walking back toward friend's room] Can I call you back later? It's my friend's birthday.
Mom: What was that? It's your birthday? Happy birthday to you!
My mother wanders off, and my dad comes on the line.
Tom: [extremely sadly] Dad... Was that really my mom?
Dad: Yup, that was your mom all right. (那就是你妈.)
