I liked this example of how what separates also connects. I thought about patches sewn together. The stitching does separate the two patches but it also connects the patches together.
I once heard John Friend talk about how it is normal for us to look around and see what separates us from others. That is a stage in child development, being able to see what is different from me and you. See that person is black, that person is tall, that person is male, that person is has an accent... These things also connect us too. We all have a color, we all have a size, we all have a sex, we all make speak.
