Very Exasperated....

Today actually was my happy and great day but after i went to work..the condition has changed... After when I have already punched my punch card, a guard shouted to me suddenly and said 'Why u waiting at there' with a very loud voice...Then i answered him back,'where I got waiting ' ...Then he said'U don't said 'LANSI' word with me...When he said that , I feel very want to box him...But after on motor, I think..Why i angry with this type of people...He only a guard,'there is no point quarrel with him, I have a brighter future than him so I don't need quarrel with him...So I just forget it...
