When you’re in the company of older people or those you consider to be your superiors or of high-rank, never sit cross-legged as it is seen as a sign of being disrespectful. This practice may not be as frowned upon to some people and they may be lax about it, but if it’s in a formal setting, it would be better for you to kneel and not sit cross-legged.
