My sister and I said goodbye today after a visit lasting almost three weeks. We explored Singapore, northern Vietnam, and northern Thailand before returning to Singapore for the weekend. (Blog posts in progress!) She left mere hours ago and I miss her.

Whenever I leave my family after any length of time at home, I experience a sense of restlessness, an inability to focus, loneliness, and a hint of anxiety. I recognize those emotions in that order every time. I felt the same way as soon as I hugged my sister goodbye. And I laughed inwardly because I hadn’t expected that at all.

We don’t talk much when we’re apart and we have a history of becoming very easily frustrated with each other. We’re stubborn in different ways, readers of usually different works from different schools of thought, and very different in our habits and preferences. But we’re both independent, open-minded, and flexible. We often have similar goals but very different approaches to achieving them.

So while we traveled, explored, and experienced three different places, I felt like I was doing the same with our relationship. I learned a lot about my sister, about who she is and who she is to me. I learned about myself, too, which is what happens whenever I begin to really see other people. We had some conversations that have made me think and question and others that have added new layers to already complicated ideas.

She’s always been my sister, but we made the choice a long time ago to be friends. The nature of all friendships and relationships change over time and ours is no exception.

For these reasons and more, I miss her already.
