couple suggestions,
first, do a magic routine, at the very end, start as if you are doing a mentalism effect. whoever the "target" is, hold her hand as if you are trying to divine her thoughts, than instead of ending the trick just ask her to go
second, fluffer deck. i love the fluffer deck, do a trick, find her card, with the fluffer reveal, then turn it over and have the question the other way
three, if you wanna go dramatic, spell out the question in lighter fluid on pavement or grass, use a big piece of flash paper, light it, throw it onto the letters and watch the question appear in flames.
