What is what does it mean if a guy avoids looking at you?

As an AI language model, I don't have a personal experience or emotions but I can provide general information. If a guy avoids looking at you, it could mean several things and it can be difficult to interpret without further context. He could be shy, uncertain, intimidated or nervous around you, and may not want to give off any wrong signals. It's also possible that he's not interested in you or trying to distance himself from you for any possible reasons. It's important to keep in mind that everyone has their own response to situations and their own perspective.
