To sum it up in one sentence, "Friends come and go. Only a precious few will stay on."
Emotionally, it may be sad. But there is nothing sad about the way life is. But there is much to be desirerdt if you do not cherish those moments that you have with your companions.
That, is the real sad bit.
Just today, we had a farewell lunch at Bathers (western food restaurant near sunset way). This friend of ours is returning to China for good and we had the intend to treat him to a farewell lunch. Mid-way during lunch, two of our collegues just so happened to eat at the same place.
The most heart-warming bit was that he insisted on paying for the meal (which isn't cheap, should be around 90 bucks in total) and under the pretext of going to the toilet, paid for our meals.
Not only that, when we came back into office, we also discovered that he had also silently paid for the other two collegues that was seating in the next table.
Sometimes, just sometimes, when we are too focused on achieving materalistic wants, too bend on saving for a rainy day, too caught up trying to be rich and successful, we tend to forget that there are much simple things in life waiting for us to see, to experience, to do. And to feel good about.
Sometimes, all it takes is to see beyond the things that blinded us and focus on things that really matters. So what matters? It's the people around you. Your family and your friends. Without them, without these basic pillars of life, no life can be meaninful, no life can be fulfilling. All you can have is only a bland mix of going through the motion. People around you are the ones that gives flavors to your life.
Remember that.
