But, it’s entirely possible to have thoughtful, deep, honest discussions with individuals over a textual medium and to develop meaningful relationships in that way. I have done so. Often these relationships start in a more open public setting and become more meaningful in a private space, similarly to real life.
* body language, non verbal communication
* the ability to respond instantly
* the ability to interrupt
* the ability do develop relationships over time
