history:  I ran into my old school mate outside the country. I could not believe my eyes; we were in a different country How believable do you think this is when you run into your old school mate outside the country 
current: i think that would be very unbelievable to run into someone out the country especially from school. Has that ever happened to you?
next: Of course yes, that is what i just said happened to me. It really caught me unaware
