What is it about you that makes you worth falling in love with? What would make someone take a second glance, ask you out, flirt with you, and ultimately fall in love with you?
In the personal ad for myself that I placed as a gag (And wound up bringing together my fiancee and I), I mentioned things like "Do you want a pair of big brown eyes gazing soulfully into yours while you take long, slow strolls on moonlit beaches? Better get a cocker spaniel then, 'cause that sure as hell ain't me", "I like to laugh until someone cries" and "Not for the faint of heart."
She says the line that hooked her was "Snarling sarcasm conceals a puppy dog heart." Hey - Whatever works, I guess...
