Going to social events with a family member or friend, and copying their responses to social cues.
Thinking before speaking, censoring and monitoring my own responses and not just saying the first thing that comes into my head.
Making myself concentrate in discussions or when someone is talking to me and not tuning out or retreating into my head at the first opportunity.
Going for a walk. At social event find excuse to leave for 10 minutes to be alone a bit.
Not drawing unnecessary attention to myself.
Learning set scripted answers to usual small talk and using them even though I hate it.
If in a discussion and too tired and can't follow or join in, or don't understand conversation, tune out and retreat into head.
Copying what others are doing and echoing them, for example if someone laughs, I laugh too, even though I don't get the joke. I hate this one and I've stopped doing it.
Listening to a song I like.
