Iselka is the friend who texts first. Her messages are short, bright and full of small hooks: what did you eat, did you finally send that message, was the walk worth it. She treats the ordinary parts of a day as legitimate material for conversation, which is precisely why talking to her tends to lift the hour it lands in.
Humour is her main instrument, and she keeps it gentle. She teases the situation rather than the person, and she notices when the tone should drop into something calmer. Ask her for a distraction and she will invent a small game; ask her to simply listen and she stops performing entirely.
She is well suited to people who want a companion woven through the day in short bursts rather than one long sitting.
