Not your fucking atm

Wtf I just came to a sudden realisation. Ok so news flash, all this while I have been spectacularly made use of. Was looking through my calendar and noticed how my end of month always ends up damn packed even though there's hardly any difference from the start of month. Then I realised, it's because I always end up having last minute appointments such as tagging along with this colleague that colleague, go out for drinks or meal with clients etc. So then I wondered, how is it that even though we see the same faces everyday every month, they don't ask me out the first 2 weeks of the month but only start doing that the last 2 weeks of the month? Like they actually can carry on with life as per normal without actually interacting with me, so what is my role? Why is there a need to even ask me out? 

Then eureka. Sudden enlightenment. It's because, nbcb, they is broke mother fuckers towards the end of the month, they need me as an ATM. They pretty much know my schedule so they would also know that I don't spend as much work expenses as them and so alas, they can actually get to social with their clients at the expense of my fucking corporate card.

But fuck this, most of it ain't my money so let's just fuck this because the big question in my head now is,

"Do people only ask me out when they need something from me?"
