Rescue teams searched every inch of that lake and the surrounding woods for days on end. They found absolutely nothing. No trace. No goodbye. Nothing at all.
Eventually, the police sat my husband and I down and told us the truth we didn't want to hear — that with a current as strong as it had been that day, there was simply no way Owen could have survived. He was officially declared dead.
I genuinely did not know how to keep on living after that day.
I was in such terribly bad shape that I had to be hospitalized for observation. I couldn't eat. I couldn't sleep. I couldn't even think clearly.
My husband quietly handled the entire funeral arrangements himself. I simply could not handle a single thing.
Even just standing there beside the casket felt impossible. My weak legs were barely holding me up.
I felt completely hollow inside.
Weeks slowly passed. I had only just barely started forcing myself to eat tiny amounts of food again.
Every single day, I sat alone inside Owen's empty bedroom, surrounded by all of his things, staring into a silence that felt absolutely unbearable.
Then yesterday afternoon, my phone suddenly rang.
It was Mrs. Dilmore on the line. She had been Owen's seventh-grade math teacher. He had completely adored her class. He talked about her all the time.
Her voice came through the phone, shaken and uneven.
"Good afternoon… I'm really not sure how to even explain this to you," she said softly. "But I just found an envelope inside my desk drawer this morning. It's from Owen. It's addressed directly to you. Please come down to the school immediately.
My old heart nearly stopped beating right there in my kitchen.
I grabbed my jacket off the hook and drove straight to the school as fast as I could.
Mrs. Dilmore was already waiting for me by her classroom door, her face completely pale. Her trembling hands held out the envelope toward me.
