Okay, admittedly-- if you play this half ass, then she will find out you lied, but what if, instead you went for it?

First, you meet the girl of your dreams. She's super hot, and even willing to help you find your lost falcon. When you're heart broken, you take the bonus consoling, but end the date with a hug. Sure, you could score some sweet ass... but this is the girl of your dreams here, bub. These things take time. You end it with a tear filled hug and perhaps a kiss on the cheek, but because you're a suave falconer, you scored her digits and now it's time to move on to the next part of the plan.

Three to five days later, you still haven't seen your falcon, so you have no choice but to call her, because she's the only one who understood your pain. Here's where you have the chance to figure out if she's the one. Sure, you're broken up about the falcon, but it's time to find out more about her. A phone call and an email or two later you're ready to be around people again, and she's the one you want to be with when you do it.

She finds this incredibly hot, and her mothering instincts kick in a bit--so now you get to find out if she'll be a shit mom or not. You meet her at a restaurant-- sitting out on the patio, so you can stare longingly at at tree or two-- reminiscing about 'ol Flaconey, but not so much that you seem needy, you're over that business and ready to move on to your next thing. (Cheesy grin here so she knows you're embarrassed to have admitted that so soon.)

When the date is over, it ends in a kiss, you're in mourning-- don't try to touch her boob.

And the third date? That's when you invite her over for homemade spaghetti. (Get the kind in a jar, no one can really tell the difference.) She'll ask where your falcon stuff is, and you'll tell her you gave it all away on Craig's list because it was just too much to bare.

She'll hug you, this time... you're home free-- go for the boob.

TL;DR: It won't work unless you totally go for it.
