social battery

This kind of metaphorical battery powers your social life.  If you socialise too much it can be drained, leaving you without any energy to relate to other people.  You will need to recharge it before you can go on, and possibly cut down on your activities in the future so that it doesn’t go completely flat.  Not good for a battery or a human being.  There are some odd suggestions for how to run your social life to preserve your battery.  Go to a social occasion pretending to yourself that you are a detective who listens and observes the behaviour of others.  This makes a game of it and means that you expend less energy on others.  In similar gamifying style you can have a bingo card set of topics and types of people and tick them off as you encounter them.  Be prepared.  Have a topic of conversation or interesting few lines to use as a starter to a conversation.  The reverse game is to see if you can spot the person who is preserving their social battery, and avoid them.
