Both Athan and I. LOL
He started it! We helped fanning the flames. LOL We thought it is a great hobby and good for his brain development, so we kept feeding him more puzzles. And who knew, this brought back the passion I once had but buried for many many years (God knows why). I was a total puzzle maniac. However during my move to Auckland I sold off/given away my puzzles keeping only two, for its sentimental value.
You know what this called? 吃飽撐著沒事做! Hahahahaha
