One day you invited your best friend Xiao for a night out. You had a good time, after a while you both went to sleep.. You were sleeping on the bed and he was sleeping on the couch next to you.. At night when you were sleeping someone woke you up by poking your arm.. when you opened your eyes you saw Xiao standing over you... when he smiled he whispered ..

"Hey.. My pillow is getting kinda boring... Wanna replace it?"
