Double Surprise Proposal

After finishing a lackluster b'day dinner, my longtime girlfriend is completely unaware that inside of my friend's darkened living room I have ammassed a surprise birthday party full of her good friends and family.
To make the startling surprise work, every single light and cellphone and autofocus sensor has been hidden so the sliding glass door can act as a two-way mirror.
The guests can see out, but Nicole won't be able to see in...
Thanks to everybody who came out on such short notice. On the evite, tears were promised... I'd say we delivered!
Look forward to seeing everybody at next party April 10th!
