Random (Body) Conversations...
Here are two short conversations (for obvious reasons) which might start to show where and why stereotypes come from.
The first is an honest-to-truth conversation with one of the English teachers (ET) at my school.
ET: Hello. You have a fold in your eyelid!
Me: Yes, I do.
ET: Some people in China now have surgery to make a fold in their eyelid.
The second happened in BeiJing, on my way to a youth hostel. After the normal "Where are you from? What do you do?", this comment was made.
Man: 你的鼻子很大。 (Your nose is big.)
Me: Uh, 谢谢你。 (Thank you.)
