you claim to know TimBL and he also claims to know you.

|  Here's how to specify that in Executable English


a-person and TimBL are at 1 degree of separation in a social network
--------------------------------------------------------------------
1. that-person is permitted to sign up


TimBL knows a-person
----------------------------------------------
2. that-person is allowed to access a resource


a-person claims to know TimBL
TimBL claims to know that-person
--------------------------------------------
3. that-person can alter a resource ACL rule


a-person and an-other-person are friends in Facebook
-----------------------------------------------------------------------------------
that-person and that-other-person are at 1 degree of separation in a
social network


an-other-person and a-person are friends in Facebook
-----------------------------------------------------------------------------------
that-person and that-other-person are at 1 degree of separation in a
social network


this-person and this-other-person are friends in Facebook
==========================================================
   TimBL           Kinglsey

TimBL knows this-person
========================

this-person claims to know this-other-person
