I have been and always shall be your friend. — Star Trek II:   The Wrath of Khan

Friends are hard to come by.  Friendly acquaintances, fellow travelers, and temporary companions are easy and common.  But people you will help without asking, support with no obligation, and give hell to with a smile are rare.  When you can find them, count yourself lucky and then do nothing that betrays the trust it takes to call someone ‘friend’.
