* Respect: In some cultures, covering one's hands can be a sign of respect or deference.
* Nervousness: Sometimes, people will sit on their hands to keep themselves from fidgeting, which can be a sign of nervousness or anxiety.
Negative:
* Hiding something: If someone is sitting on their hands while they're being asked a question or accused of something, it could suggest they're hiding something or being untruthful.
