In China, saying please and thank you to close friends and family members is considered rude (that you don't consider them very close). It bugs the shit out of my wife when I say it.
Since I work the front at Mickey D's, I say thank you ALL the time. Sometimes I say please, but that's mostly to supervisors as I BEG for a break or to get off when there are 3 people to cover what I do. lol When asses thank me in a sarcastic way for some shit that I know they aren't really thanking me for, I ALWAYS say "no problem". lol I also just say it...no smile. lol Otherwise, I'm a smiling, thank-you and your welcome kind of gal.
Think is say it too often, that it may cause annoyance. Maybe i ask too many favours / am around wonderful people that are helpful.
I just stopped saying thank you around her family. Which is easy, because they're 10,000 miles away right now.
I've grown up with the Western way and adopt it very traditionally, but I can actually understand that, from when I was very little, learning Western manners. When I was 2 yrs old, I had all this "please, thankyou, excuse me" stuff rammed down my throat. I remember one of my brainless family demanding that I say please and thankyou etc for something concerning dinner. So I said "well if I dont beg please, are you going to starve me?" The reply was "its called being polite". So I said "well you're hardly being polite to me" ie I'd decided that their reasoning was a bit circular. I felt they were up to a power game. I think manners should be less about absolute rules, and more about circumstances. Often its the rudeness people that try and stamp their feet in a tantrum about "manners". I suppose in China, there's the issue of what is a fair request, what is ingratitude, rudeness etc etc. ________ Similarly, in Britain we are told that you should adopt small talk at the start of a phone call before you are asking for something. I actually prefer to discuss business, and THEN make small talk. Certain countries, for instance, the USSR were known to do it that way more, as a rebellion against what was termed "Bourgeosie mannerisms". To do the chit chat 1st just seems insincere to me, atleast instinctively. Its like it doesnt make sense.
