What is the first text message you should send when you meet her (urgent)

The first greeting should be tentative,

Don’t rush to express anything,

because the message you sent her is what you want to express.

So it should be some polite greetings, such as:

"May you be happy every day - a friend who still remembers you."

"Meet you You really make me happy, I hope you are happy every day”

…………

Wait until the other party responds (you will know how the other party feels as long as the other party responds to the message) ) and then send some messages that express your emotions.

In this way, you will appear more stable and respect the other party.
