You don't speak binary? That's okay. The bride-to-be explains what happened:
My boyfriend told me I had to close my laptop for a couple minutes, then when I logged back on this was posted to my facebook wall. He sat across the room as I transcribed and then decoded it. After about a half hour I found out it says, "Rachel, you are awesome. Will you marry me?" I said yes, of course :B
Marriages that are founded on ones and zeroes are the only ones that are stable and healthy because there's no such thing as two.
