Life's Lessons..

My girlfriend invited me to her house, I found her sister alone in the house, she was unbelievably sexy, she whispered in my ear, "i have feelings for you, shall we have s*x" , I immediately turned around and walked to the front door to go to my car, I found my girlfriend standing there, she hugged me and said: "you've won my trust"... Moral of the story: always keep your condoms in the car.
