Well try to talk to her about things she likes !!
Try to say comic things , even if she don't cares.

If you can't , just jump over a window

Yeah man 12 hours is slavery, you don't work for living , but
you live for work man !

I also have a guy in front of me at work, but 7 hours a day , and i have not him in front of me when i go dinner or to toilets. We don't talk a lot , and we have work that's make us focus on work instead of ourselves.
But sometimes it's painfull , in that moments i look at comic pictures or soft sexy things over the Net to keep a relative mind and it makes me laught about ourselves two in the same room !


And yes LordMoggy : YOU NEED A DENTIST !!
