Thai Traditions and Customs
Public displays of affection are common between friends but very rare between a romantic couple, it is uncommon to see a Thai couple kissing or holding hands in public places, however the influence of modern western culture through media and the internet has slowly started to change this.
In all countries there are traditions and customs that should be noted and respected and Thailand is no exception to this rule, but if you do not show any disrespect to the 3 pillars of the nation; monarchy, society and religion then Thai people will usually be polite and will avoid confrontation.
To touch someone on the head or to point the soles of your feet towards someone is very impolite, as a matter of fact, the foot is considered as an unrefined part of the body and the head is considered a high and noble part of the body.
In the same way, touching or using your foot to indicate something is regarded as an insult.
You must also avoid showing your feet in front of a Buddha.
It is very disrespectful to step on Thai coins or bank notes because the portrait of the King is printed on them.
When you enter a house, you must take your shoes off and avoid stepping on the doorstep (siege of the house of spirits).
