What cultural faux pas should I try to avoid making in Koh Lanta?

"In Koh Lanta, it is considered disrespectful to touch someone's head as it is regarded as the most sacred part of the body. Avoid showing the soles of your feet to others as it is considered rude. It's also important to dress modestly, especially when visiting temples or other religious sites. Public displays of affection are generally frowned upon, so try to keep affectionate gestures private. It's also considered impolite to point with your finger, especially at monks or images of Buddha. Always use your right hand when giving or receiving something, as the left hand is considered unclean. Avoid discussing the Thai royal family unless it's in a very respectful manner, as it's illegal to defame, insult, or threaten the king, queen, heir-apparent, or regent. Lastly, try not to raise your voice or show anger in public as it is seen as a sign of losing control and is viewed negatively," said another expat in Koh Lanta, Thailand.
