Show her your gun collection. Immediately afterward tell her that you don't take rejection well and also let her know just how many people in your country/state/town/neighborhood you hate.

Be sure to inform her what a Jacketed Hollowpoint .45 round can do to an unarmored target. Remark that "they" are out to get you.

Then compliment her on her shoes and perfume.

Then let the good times roll.
