3rd party?

Venue: Sunway Pyramid

Him: I met someone just now. Guess who?
Her: Hmm....(wondering if it could be his ex)....dunno, who did you meet?
Him: My ex's best friend.
Her: (Awkward) Oh I see....so did she greet you?
Him: I think she saw me but never intended to greet me. I greeted her first.
Her: Okay...was she okay to see you again?
Him: Hmm....it's been so long and we are all grown up. She is currently working in KL, your company subsidiary.
Her: Was she alone or with someone?
Him: Alone, shopping. She asked if I came here alone too. I said I came with my wife.
Her: (Happy) Ohh...the news will spread, so I guess you will receive MSN message from your ex in the next few days. :p
Him: Actually, I have already received her message 2 days ago. She congratulated me for our wedding.
Her: Is it? You never told me that.
Him: Nothing important. I only replied her with thanks.

Bandar Sunway is where his ex lives. Sunway Pyramid is the most popular shopping mall within the area. It is also one of the favourite shopping venue of his wife. What will happen if three of them meet again? Will his ex still regard his wife as the 3rd party?
