my small world encounters

Bumping into friends, classsmates and acquaintances in strange places and under weird circumstances..... is the story of my life. Here are my top encounters:

1. I met up with a high school friend who was in town for a week and she brought her college best friend (whom I have never met before). While chatting, I discovered my friend's college bud usually hangs out in the same building where I live. So we decided to exchange numbers, so much to our surprise, when I asked her to dial my number so that I can save her number. She blurted out my full name (reading from her phone book). I was already in her phone book!!! It turned out, she's my second cousin and her mom asked her to save my number in her phone and look for me when she gets here in Manila.
2. On our trip to Macau, my friend Helen and I were supposed to meet a Filipino based there but unfortunately he wasn't available during the days we were there. So on our first day in Macau, we decided to explore on our own. While we were in a crowded bus, Helen ended up talking to a Filipina. Right after she introduced herself to her new friend, a guy seated behind me suddenly patted me my shoulder and asked if my friend's name is Helen Sophia Chua. I almost fainted. How can this stranger know my friend's name? It turned out he was the guy we were supposed to meet. So we ended up spending a few minutes strolling the streets of Taipa, one of Macau's 3 islands.
3. It was my first trip with my brother out of the country. We took the MRT from Sentosa. Upon boarding the train, I suddeny saw a familiar face, it was a college friend of mine, Gay. We were there in the same car, I stared at her for a few seconds and I had to blink to check that it was really her. Then I shouted, "Gay"! She was as shocked as I. I found out she was there to attend a wedding while I was there for a few days.

What are the chances of these strange encounters happening?

I'd like to believe they happened for a reason....Maybe to make me realize how small the world is...
