Forgive me for being sceptical

I am pretty sick of hearing words boy... time and time again your promises have proven to be nothing. I am especially weary of this time, though i will not involve myself in anyway. Good luck and may God forgive you if you make ur mistakes yet again. I had hoped you had changed, had built a little confidence in your nature. But its beyond rockbottom now. Enjoy, you lying bastard... what you have done, i have experianced... on the victim's end... and that this time the victim is sm1 i actually know and have grown to care abt... it makes my blood boil to even think about it...

Physics down... a mega tonne of work more to go...
