Culture is people's way of life and it's everywhere. From the outside world to your small group of friends. Culture defines many things in you; your dressing, language etc. But when culture takes it place be sure to keep your personal identity. Don't struggle to blend in a community and lose yourself. You have your goals and standards.
Like, for a christian, keeping faith in University setting is always difficult to keep through. But you know you can't compromise. Faith affirms, confronts or transforms culture. So Christians lets practice discernment. Not everything that is legal is right.
