@SS: Yes you are. We may strive not to be that 'petty' but it doesn't mean we succeed. That we don't fall prey occasionally to those immature feelings that make us act or feel a certain way, especially when we're fearing something and are not paying attention to how we're impacting others *becoz* of that fear. Even worse when we try to deny said fear is even present.
It may be our aspiration to not fall prey to such emotions and yes, we are capable of rising above them, but that doesn't make us immune to them, which is why we need to be vigilant to be able to rise above them. Everyone can become distracted or consumed by fear though and that would cause us to just like anyone else become a victim of this behavior.
