变式题：
题目：Your Chinese friend says, "You look older than your photo." Your American friend replies, "Oh, I'm 12 years old." Why might the American friend feel uncomfortable?
A. Because 12 is too young to talk.
B. Because asking about age is considered private in Western culture.
C. Because the friend doesn't like photos.
D. Because the friend is shy.
解答过程：：
1. 识别语境：中国朋友夸对方“看起来比照片老”，在中国语境下可能是赞美成熟或关心，但直接涉及年龄。
2. 文化对比：在西方文化中，年龄（尤其是成年人的年龄）被视为隐私，直接询问或评论年龄可能被视为不礼貌或冒犯。
3. 推断心理：美国朋友感到不舒服是因为触及了文化禁忌。
4. 结论：选B。
