"Psycho call"

Yesterday japanese called at my phone.
Mr..?:Can you speak english?
Koy:er.. yes
Mr.?:Can I speak to Mary?
Koy:I'm sorry,you have wrong number.
Mr?:err.. Listen I'm Mary's boyfriend!!!
Koy:...Mary's not here and you have wrong number
Mr?:I want to speak to Mary!!!!
so I hung up the phone because I thought he's psycho man-His sound like
he's doing something and he's so tired
~>_<~ I'm so scared.
