Without body language or voice, your words carry everything. Here's how to make sure they carry what you actually mean.
'That conversation meant a lot to me' lands. 'Cool chat' lands nowhere. Specific words are how feelings survive text.
'Honestly I'm a bit nervous but also really curious' gives a much richer picture than 'I'm fine.' Both-and is more real than either-or.
One quick read before you send catches 80% of misreadings. Would a stranger understand this the way you mean it?
When you take time to say what you really mean, you're treating the other person as worth the effort. They'll feel it.
