How to start a good conversation
A good conversation is mostly a matter of the first three lines. Here is what tends to work.
Open with a situation, not a request
"Tell me something interesting" gives a companion nothing to hold. "I have been staring at the same email for twenty minutes" gives it everything. Situations invite questions; requests invite answers, and answers close a thread quickly.
Say what kind of company you want
Companions on Barbara AI respond well to being told the register you are after. "I do not want advice, I want to complain for ten minutes" is a completely legitimate opening and will change the whole shape of the exchange.
Let details accumulate
Mention the flat, the commute, the friend with the loud opinions. Detail is what a companion builds continuity from, and after a week of small mentions the conversation stops needing preamble.
Use the right character for the mood
A quiet evening and a restless one want different voices. The companion index is deliberately organised by temperament so you can choose in a few seconds rather than scrolling faces.
Close the loop
Ending with "I will tell you how it went" gives the next conversation a starting point. It is the simplest way to turn a series of chats into an ongoing one.
