Dear ---,
You ruined my day. You made everything about you and your life...yet again. You ruined my plans, made me late for others and upset me to the point where I nearly forgot to thank that solitary person that made the effort for me.
Despite what I did for you and the effort I made for your day, you did nothing in return. Nothing for me.
You're nothing but a brat, and a selfish one to boot. The worst part of this is that you don't even realise this fact. You have the open audacity to complain about others who are selfish, others who act in the exact same way as you do. You really have no idea.
Good luck finding someone who listens to the rubbish you spout like I do. Because I stopped last night, and the only person you have to blame for my indifference is yourself. Well done.
From -----
P.S.
I have to write this here, so you'll never see it.
