Inconsiderate encounter again

Last night while I was trying to sleep around 11.45pm, one lady from my block talked so loudly in Chinese. She was chatting away happily, probably on the phone.

She really pissed me off and I shouted out of the window "安静啦！几点了？讲话还那麽大声！" My voice was so loud and I can hear the echo in the silent night. I think the whole block can hear me, though I stayed at 20th storey.

There was no sound after I shouted. It's quite obvious that she knew that I am talking about her.

Really can't stand such inconsiderate people!
