I don't get it.

why people hit on the lift button repeatedly when the lift is going to arrive at the same time anyway. more hits on the button doesn't make the lift arrive faster, does it?

i don't get why people type in CAPITALS to capture another person's attention during instant messenging, when the other person is at another window. it's not equivalent to shouting, hello? (but i'm rather guilty of it though)

and i also don't get why people nudge repeatedly when the other party's status is set to Busy mode. they can't see no nuts baby, it's useless. :D

well, just food for thought.
