Why are some people so inconsiderate?

Some people are just so damn inconsiderate......So what happened exactly???

Yesterday after my POA class......I went home......

So.....the train was packed with people.....There was hardly any space for me to move......Finally, it was nearing to my stop......so I had to squeeze my way to the front......As there was simply too many people in front.....I had to keep saying 'Excuses me'......and keep squeezing to the front......then the passengers boarding the train also keep coming in.....I can't understand why they simply can't wait for those alighting to come out 1st......I nearly can't come out.....it's like fighting a 'tough battle'.......

After that I started to walk home from the MRT station.....on the way.....there was a group of Malay girls standing in the middle of the pathway......don't think what they thinking about....standing in the middle of the road talking away......Can't they see they're blocking the way n that people are trying to move past them??? It's not exactly like they're very small or invisible.....so they're blocking the way...n I can't get past them.....so I said 'Excuse me' n guess what??? They still stand there n talking away.....n didn't move at all......by then I was really fed up(with the earlier incident on the train n now this).....I didn't bother to say excuse me anymore.....I just squeeze past them.....fuming away......

Why am I so unlucky??? Meeting so many inconsiderate people in one day....It's just not my day.......
