Missing In Action

Oh my gosh my cellphone is missing in action.Like two hours ago my husband called and told me that our son called him.My son really loves playing with my cellphone.I have been looking for my cellphone for almost an hour now and I cannot really find it.I am really getting pissed,I know it is my fault because I just put my cellphone every where.My husband has been trying to call my cellphone but I cannot hear it and sometimes it get out of reach.Grrrrrrrrr I am really getting impatient now.I do not know where to find it,I have tried checking my son's room,my room,the bathroom,the living room,the kitchen,his toy bin,his bed but I do not find anything.I just hope I will find it before it gets low battery.
