Hi, my name is sabrina I'm from pakistan 21 yrs old
My parents want me to marry this guy who is in pakistan and he is 20 yrs old my parents like his family and everything and they say he is a good boy as well. I have seen his picture and he is very good looking but I don't know him as a person so my parents said I can talk to him on the phone and get to know him.
I think its hard to get to know someone just by talking to them on the phone so I need your guys help what kind of questions should I ask him or how would I know what kind of person he is just by talking to him

Those of other cultures can not judge how other cultures react and do other things, While in the US arranged marriage is not the norm but in your culture it is not unheard of.

In the end any relationship even an arranged one can work if you and the other person are willing to make it work.

Well we don't arrange marriages, however to get to know someone
I would ask what they enjoy doing with their time?
If appropriate ask what their friends are like.

Let him do the talking, and see what he is about. Get him to talk about himself, and what he thinks about a variety of things, that are important to you.
