The smile you have on your face when she looks at you doesn't have to be for her. It doesn't have to yeild any obvious results. No doubt you'll be driving her nuts because she's always nasty to you but she can't wipe that smile off your face. One of two things, you'll eventually crumble her walls or she'll give up trying to intimidate you. Don't give up your power to her! Did you read 'Beauty is in the "I" '?
Here's another saying for you:
"Fake it till you make it."
"It's not what you gather, but what you scatter that tells what kind of life you have lived."
