Text Is the Handshake
Every meete chat online starts as letters on a screen, and that is fine. A message is low-risk: you can test the humor, check the pace, see if the other person actually reads what you write. Two or three good exchanges tell you whether this deserves a voice.
What text cannot do is finish the job. Tone flattens. Sarcasm misfires. The person who is hilarious in paragraphs can be impossible in person, and the quiet texter can be the best talker you meet all week. You will never know from a keyboard.
