In the night, आप can hear some footsteps outside your window. या आप probably will hear some knocks on your window. But if आप really want to know if he's visiting आप या not, आप can just put a फूल अगला to your window. And make sure the window is unlocked and not closed to thigtly. If आप wake up in the morning and the फूल are still fresh, then Peter has come in the evening to replace the flowers. Try to put the फूल आप put are roses. But if the फूल withers, don't give up. Keep believing and don't lose hope :)
