Agree. As I am a C9 who wait for my littled kids at teh schoold bus station everyday, I could see lots of Yans and Buns there.
Yans are usually seductive with their mode of dress while at work, dating Pakistan, very low discipline, inethical, sees money as more important than their lives.
Buns are with higher dignity (don't want to be scolded), but some has the passion for the kids they take care. They don't mind working extra hours provided you have good relationship with them). But of course, if you always scold at them they won't be willing to. Seductive in the way they dress but only on hoildays. They date Western men (I guess a little better than Pakistan). They usually call, in their own language, their little boss as their "son" or "daughter". I could see they always discuss about the kids they take care among themselves and sometimes see them proud of them by while how smart the kid is.
Maybe I'm biased but indeed I have seem a number of good Buns and lots of bad Yans in my daily life.
I had yan & bun. Most bad experiences came from Yan, even meeting with those 靈體。
agree with fionacat that 非正式統計,多數心狠手辣嘅,做d好唔文明嘅嘢都係印,菲會計較d + self-center & 要面
