Congrats man, I just got engaged yesterday actually so good luck.
Our first date was at a nice chinese restaurant and we kept all of our fortunes from the fortune cookies over the years. So when we got chinese yesterday, I went by the place earlier that day and picked up some fortune cookies and broke the first couple but eventually inserted a custom "Will you marry me" message into her fortune cookie and then when I picked up the food later I gave her that fortune cookie when I put the food on the table.
I couldn't wait that long, I proposed the day after I got the ring.
