ppl without any sense of responsibility!!!!

I think the worst thing one can ever do is to be made to wait! That’s the worst treatment one could ever give to either friends or loved ones or simple anyone. It has been often said that the best thing to do while waiting is to go and do other things to kill time. But whatever it is, one should have a sense of responsibility to inform others of their delay in arrival. They should think of the consequences of what their late arrival could cause the other party to lose. The least they could do is to call or send text message to let the other party know and not let them wait in vain.
Tsk tsk. Why do people simply prefer to ignore how other party would feel and not bother [“hack care” in Singapore slang] about informing.
Sigh!
What shall I do with these people without having any sense of responsibility!!!!arguhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
