My friend introduced me to a girl I haven't met yet. It's always embarrassing to text her. She asked me to call her and say anything as soon as the phone was connected.

Love is to show her reserve, girls, this is normal.

She asked you to call, which means you may still be.

Just say, did you eat? The weather is very hot recently. You should be careful to prevent heatstroke. What do you usually like to do, go shopping or surf the Internet and play games? By the way, I just heard a joke, which was super funny and said yes. ...

That's all. It is normal. Go on according to her words. If she is in a bad mood, comfort her. If she is willing to talk, you should listen carefully. If she doesn't say anything, tell jokes to amuse her.
