Posted by LillyPetalThank you so much LillyPetal! I think that's a really fantastic idea.
I would include a subtle, yet distincitve, clue so that she would comfortably guess it was me but smile at the idea that no one else would get the inside joke, if you will.
Women tend to be instinctually cautious (it's all about survival), but if she can be confident it's you (perhaps send an ambiguous text hinting at her secret invite) she may go for it.
Best of luck! Why the hell not start off the new year with a bang?! What do you have to lose! CHEERS! ?
