I want to introduce an object (female) at home. I haven't seen her before. What should I talk about on the first phone call?

First of all, you should have a normal heart to try to communicate, and you can't have resistance, whether it is introduced at home or found by yourself. Leave a humble and sincere attitude to the other person and ask her some hobbies, living habits, future plans, etc. Speak humorously, avoid embarrassment on both sides and create a harmonious and happy atmosphere.
