Cách sử dụng
The expression "not all there" means that someone is not mentally or emotionally stable. It is used to describe a person who may be absent-minded, forgetful, or not fully present in their actions or thoughts. This expression is often used in informal situations to suggest that someone is a bit strange or unusual. For example, if someone forgets their keys or walks into a room without a clear purpose or presence of mind, you might say they are "not all there." However, this expression can be considered disrespectful if used to describe a person with a mental health condition.
