Sorry, I usually don't notice when someone uses sarcasm on me. But no worries, there might be signs that we are to be together. For instance, what is your coat of arms?
There are plenty of St. Joseph's churches, Gotta be more specific. Honeymoon in Paris, then off to a small Caribbean island.
Take her for a walk on the beach. Or if you don't have a beach nearby you can use a river instead. On the walk, whisper sweet things in her ear, like "if you were the moon, I would want to be the sun to give you all my light". Also blow in her ear and nibble on her earlobe after you whispered a few sweet words. Success guaranteed.
