I found my girlfriend at home. Her parents and mine are business partners. The first time we talked was when I called her. Or should I text her?

Making a phone call is more sincere, and there is more room for text messages to turn around. If you are outgoing, generous and direct, you can make a phone call directly. If you are introverted and elegant, just send a message. After the communication, you can think about her conversation carefully. If you talk more and take the initiative, it will be a bit interesting. A little more manners, a little less manners, unfamiliar for the first time. This is normal, you can work hard.

It doesn't matter what you think of your personality, as long as you can talk happily.
