My friend introduced me to a girlfriend I have never met. What should I say when texting for the first time?

See what you are doing by texting. Send it if you have nothing to do, and then say, "Ha ha, (Hello! What are you doing now? I am XXX. " Then she tells you what you are doing, and you can continue talking to her! The "hello" in the middle can be added or not according to your situation!

If you don't answer it, it may be something or you didn't see it, then you can call and have a look. Boys should be bold and take the initiative!
