So this was actually posted here a while back either as a post or in the comments but it can do wonders:

Randomly, text her a silly picture of yourself. I started with a self picture of me in the car, tongue out (I was stuck in traffic). The silliness shows confidence and not giving a crap. Then, include a message like 'and with this picture, I officially declare a picture war with you.'

Her response will probably be a shocked one or something like 'hahaha'.

Respond to her by saying: 'there is only one rule in picture war; you can send a picture of anything but it can't be a picture you took in the past'.

This could lead to very, very interesting pictures.

TRY IT! And let us know your results in the comments.

EDIT: in case it wasn't obvious, the idea of the game is that you send a picture to her and she sends a picture to you. rinse and repeat
