How indispensable are you?

My mum has been nagging at me since I have been working very late recently. Not because there was work to be done. The company is rationalizing, so everyone was sticking to their desk like glue after the nominal going-home time, to show how indispensable they were. I had more than my comfortable ration of nocturnal MRT travel recently & it is starting to get on my nerves. It's silly right? But I can't be seen leaving early while everyone is staying back!

I long for the good old days ...sob...
