Yes, i remember the first time my mom ever rode on my dads bike (87 yamaha royale) everytime they went around the corners she would lean opposite of my dad, because she didnt want to be that close to the pavement....The first time we stopped the general consensus was if you dont lean your gonna be on the pavement.
Whatever you do dont let her talk you into shit. I had a girl get on my bike and after cruising around she asked me to go faster..so i went a little faster. Next time we stopped she asked me why i wont pop a wheelie with her on the back...i wouldnt do it. She would stand up ocasionally, and being on a sport bike you know where those pegs are. Then theres the turning on the highway crap. she wanted me to take a particular exit, rememeber the guy with his head sticking out of the back of the semi trailer....that exit, and i didnt want to do it 2 up, she grabbed my jacket and leaned...i had to take the exit...its okay though i took her straight home and never took her on my bike again.
