Relationships are all about compromise. It's truly a turning point in your relationship when you decide to compromise on something important, whether it's relocating for your partner's job, working overtime to pay the rent while they go back to school, or letting their sister live with you when she breaks up with her boyfriend. But what makes a relationship special is compromising with a good attitude. If you are happy to do what it takes to make your partner happy, and you don't hold any grudges because of it (and vice versa), you'll know you have what it takes to go through life together.
