Friend? Yeah, right?

I don't have many close friends, and tend to keep my true thoughts and feelings to myself most of the time.  This isn't dishonest, I just chose not to open up to those I don't trust.  Burned too many times?  Yes, of course.

My best friend (from the age of about 6 or 7) and I sort of drifted apart around the age of 14, and maintained a cordial relationship after that.  We went our own way, got married, had kids, and about 3 years ago we bumped into each other in the supermarket. 

It was one of those : "Oh my gaaaaawd haven't seen you for years how are you?  Kids?  You had boys right?  How's work?  take my number and call me when you can?  gotta dash. lovely seeing you."  Of course we didn't call.  Then I got an invite to a party she was having, but couldn't attend.  We didn't see each other again until about 12 months ago, then suddenly we clicked again.  It was as if we had never been apart.  Truly good friends.  We speak almost daily, otherwise mail or text.  We see each other at least once a week.

I had another friend.  She was young (which may explain this) but we also had clicked.  We worked together and socialised.  I shared with her and she shared with me.  She had a level of maturity that was not in line with her age.  After I left my job in December, things tapered off gradually.  I called her, she was busy.  I msn'd her, she was busy.  I texted her, she was busy.  Eventually, she popped around to visit, I went for 'family dinner' a couple of times.  One day I decided to ask her why she didn't ever call or text or mail me unless I initiated the contact.  She got angry and claimed I only contact her when i want something, such as the money she owed me, or information about work. 

Naturally this didn't sit well, so I took the time to tell her a few truths and we ended on an angry note.  I decided I was done and really not interested in resuming the relationship.  Until.....

Tuesday I got mail from her -  in my Hotmail account, in my telkomsa account, and a text!  All the same... an invitation to her birthday 'party'.  Now I am really not even keen to reply, let alone attend. 

Yes, I am stubborn.  In my defense, I chose to no longer put up with other peoples shit.  I have enough in my own life without having to deal with others unhappy attitudes and negative vibes.  I made the choice to end that relationship, and won't be trying to ressurect it again.
