Walking Whores

Have you ever run into such a situation, where you got out an MRT train, and someone from behind suddenly walk past you and 'cut' in perpendicularly across in front of you and walk off, causing you to stop for a second or so just so that he or she can commit such an inconsiderate act?

What the hell is wrong with these people? I seriously think this is pretty irritating. When will they ever learn? When someone else do something similar to them? I doubt it. At least in the local context, where most people have a childish mentality, I think what they would do would be to 'cut' back...

What is the use of national education when people still lack in such fundamental areas?
