(look straight and serious into her eyes.. bear with pls, just for a while)
if she hug you and kiss your face, ripe your reward and had a good session. but if she laughed and says: hahaha..., common, get out of here....
then say: "dun you ever die okay? I'd loose the other half of the income and there goes my plan to upgrade to a 2.3 litre Camry next June"
just make sure your couch isn't occupy by your dog
