I'd start by laying some groundwork. I like to pick wildflowers, and I'd have a bouquet picked before I picked her up.

I would help her put the flowers in the vase of her choosing, then we'd go out for a slow walk to a local restaurant and eat something light and delicious.

From there--head back to one of our places and watch an old movie on the couch... under a blanket, warm and toasty. Maybe eat some nice gourmet chocolates and have a glass of wine.

Gentle kiss at the end, to increase the anticipation for the next date... release some oxytocin into the body.
