Memorize my number also no use.Unless i put my phone on my bed,even if it rings,i won't wake up lols.If it's on my bed,the annoying vibration will wake me up and i'll pick up the phone.So,depends whether you're lucky or not.And,I reckon I sleep later than you?How can you disturb me that way lols.So,you're better off disturbing someone else than me :)
Jordan also,if he finds it annoying he ons silent and continues to sleep lols.
