My fiance and I have deliberated some about it but before recently all she knew was that I got lucky on a stock. She'd take about 10 seconds after coming home at night, assess my mood then say "guess American is down again today huh?" Haha.
I have this money earmarked for my lifelong dream of owning my own airplane. Now that we're engaged the logical choice is to sell some shares to put towards a down payment on a home or towards the wedding; but she knows better than to even insinuate that I sell it for any other purpose than its intended :)
