You know just like good spellings, grammar and mental arithmetic calculation; it seems that normally accepted social etiquette is slowly being foregone. Of late, I have noticed that some people find it perfectly alright to burp loudly and that too without eating anything without so much as a blink of an eyelid. No excuse me or giving a sorry look. Horror of horrors, I caught someone passing gas loudly in a social situation without looking uncomfortable. Maybe, I am old fashioned but I found it extremely putting off.
I am certainly not a purist but there is still a place in my heart for well-turned out, well mannered and well-groomed people !
