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

"It is important to be aware of cultural differences when visiting Belarus. It is important to be respectful of local customs and traditions, and to avoid making any offensive or inappropriate comments. It is also important to dress modestly and to avoid public displays of affection. It is also important to be aware of the local language and to avoid speaking English in public, as this may be seen as disrespectful. Additionally, it is important to be aware of the local etiquette when it comes to dining, and to avoid eating or drinking in public places. Finally, it is important to be aware of the local laws and to avoid engaging in any activities that may be considered illegal," remarked another expat who made the move to Belarus.
