What is when i look at him he looks away quickly?

If someone looks away quickly when you look at them, it could be a sign of shyness, embarrassment, or discomfort. They may be afraid of making eye contact or revealing too much about themselves. Alternatively, they could be trying to avoid confrontation or seem disinterested in the conversation. However, it is important to note that everyone has their own reasons for exhibiting this behavior, and it may not always mean the same thing for everyone. It would be best to contextualize your observation by considering other cues involved in the situation.
