I finally realized and admitted that I am from stone age......

I wondered whether I am from stone age after the MRT journey. Singapore MRT system is quite similar to HKs actually. I don't know why I couldn't reach Kranji! I reached Boon Lay and should switch to another line. When I switched, I actually went back to Clementi! Since the Sungei Buloh closes at 7 and it was 5 already, I gave up and went back to town. I wasn't disappointed at all as it's one of the advantages of being a free walker--- you walk freely and you can feel free to lose your way too! :P
