Complaining about the work you do is like complaining that the shirt you just bought does not fit and forgetting that you are the one who bought it in the first place! So when you find yourself complaining, just chup up your mind and remember why you bought the shirt in the first place.
Well, what do you not like about it now?
Then why did you buy it in the first place?
Okay, so what do you want me to do now?
You want to keep the shirt and you want to go on crying about it.
You are so being unfair to the shirt who should be the one complaining actually!
Well, as you say. Let's think for a moment- The shirt was what it was, the shirt is what it is. It's not the shirt's fault if you didn't have the time and patience to try it on before buying it eh?
