Today I was organizing my son's storage box from his middle school years. I found a group photo of his junior high swim team. Back then, he was so youthful and bright. The corners of the photo are a bit worn—I wonder how many times he picked it up to look at it. My fingers traced over his young face in the picture, and suddenly a wave of emotion welled up. Honestly... I was just looking at a memory of him, but my body reacted on its own. As a mother, what should I even call this feeling?
