This annoys me...

My son's step mother informed me that they will not be able to afford to pay and help me get my son's school supplies this year, when it in fact is their turn... The reasoning behind it, is because they had to buy their daughter school stuff as well.

I'm sorry, but it isn't my fault that you had a child with a man whom doesn't take care of ALL of his children the way he should. When it's time for you to help out, stop being so greedy. Smmfh.

Sorry, end of rant.
