By then it was pretty dead. The sun was starting to slump in the sky. Most of the late-day beachgoers were gone and her friends weren’t there. It was completely quiet except for the crash of waves, the ping-ping-ping of the flag’s metal hardware striking the flagpole in the breeze, and an occasional screech of a seagull. The angel broke the awkward silence by saying, “Well, I just wanted to say thank you. Um, you know. For saving me this afternoon. You’re my hero.”I thought of Emma. Yeah, right, me a hero. My lips moved in answer, but nothing came out.She took in a sharp breath and moved away from my side a little, like she was about to say “See you” and leave. Like most girls did after a minute in my presence. It was like I could almost see any chance I had with her ticking away in those moments. Before she could go, I opened my mouth, still not sure what I would say, so I looked kind of like a fish gulping water. When I asked the question, I realized I already knew the answer.
