There are a number of reasons in which a person might act weird or uncomfortable around you. Human beings are social creatures, but that doesn’t mean that we thrive in all kinds of social situations. Maybe a misunderstood comment or an insensitive gesture can derail the dynamics of human interaction without you even realizing it. That’s normal. You just have to learn from these situations and try to grow from them in order for you to forge better relationships moving forward. Eventually, these kinds of social interactions will become more intuitive and second-nature to you in the long run.
