Backwards Walking

I sometimes encounter backward walking people.   And I’m talking full-speed backward walking, here.  Typically, there’s a forward walking person behind the backward walking person and they’re carrying on a conversation.   A modified version of this backward walking phenomenon is the person who technically walks forward, but all the while looking over his shoulder to a person walking behind him.   I can only assume that in both cases their conversation requires uninterrupted eye contact.  The result is a public version of the team building “trust fall” exercise.  I usually try to move to the side to avoid colliding with the backward facing walker, but sometimes (and true to the enabler in me) I simply mutter "excuse me" for having forward walked into his backward path, and effectively “catch” him in his trust fall.
