Lost both upper, last molars to that type of decay......first I knew of it was when an interstitial brush went awol and into the inside of the molar......I now know what a sharp pain feels like....nearly collapsed on the spot
Get them taken out before you get abscesses.
I find the lack of physical contact, hugging, kissing of close relatives odd......my wife returned to Thailand after five/six years away in Germany........and her and her mother......who love each other dearly....... did no more than politely nod, to acknowledge each others presence.....
I think you are saying Thais don't waste time on small talk?......Correct.
I would say they don't do small talk and reserve their conversations for money, food and bitching about their neighbours.
