i always do that! once a random stranger was readng the lord f the flies ( awesome book btw! ) and i wasnt finishe the page, he then turned the page, i wasn't finished so i made this complete spazzed noise until i was done... hehe
i've done this before... it makes people feel super uncomfterble! i also tried another thing on the bus! i randomly started talking to whoever was next to me.. but started the conversation as if i was in the middle of a story like "and thats how i.. blah blah blah" :3 it's fun!
