The phone rang before my alarm woke me up.
"Hello?"
"Martin, with Glass Repair Specialists. Is ten a good time for us to swing by?"
"What? ... I don't have any broken ...."
A brick shattering the bedroom window cut me off. I shook glass off my bedspread.
The brick held a tightly wrapped paper note tied with twine. I unwrapped the note from the brick.
It read, "Best of wishes! Hope this brick finds you well and in good health."
