This point is a bit extreme, but it works because sometimes in our folly we’re unable to see what’s right in front of us. Remind your parents why the caste system was originally started-for classifying people belonging to different professions.
You see each other everyday, you spend most evenings and nights out together, is more work together really the way to go? There is always a jealous person in the relationship and if you think you are the more laid back one don't get too comfortable it can switch at any moment. You will feel personally insulted by their failure even though it has nothing to do with you. You may gaze at your fellow companion and think about how good you have it.
