Selfish?

Do not dull my 'lift' By a misery you wish to spread. I am not having any part of it. Nor will I sit... Listening to you retread your dread. Oh no! I've let that go. And I'm not going to advise you, That you should too! Oh no! We've gone over this. Much more than I care to admit. You enjoy being witty in a pity I find sick! And not one part of it, This time... Will I let it stay on my mind. This time... You will find, My steps making tracks. To leave you where you sit... With your troubles on your back! I am no longer available, To share in your weeping willow business. This time... I'm donating all aspects of my energy, To the production of my own happiness. Selfish? When it comes to my peace of mind? Of course! I've done the remorse routines.
