Extroverts.  The life of the party.  The folks with the fascinating stories.  The people who get other people together to make things happen.  The host is sorry to see them go.

Introverts.  The nearly-invisible.  The ones who think that “talk” is a four-letter word.  The mountains who never come to Mohammed.  Well-acquainted with the snack table.

Juxtaposers.  The one-to-one ones.  Once they find you, they are always at your side, and you are beside yourself trying to escape.

Observers.  Looking on, taking in.  Occasionally joining a conversation to share one of their  studiously rehearsed opinions.  Living life as a limited engagement.

I’ve been each of the above, at various times.
