There is no material price for everything.Coming from someone who is materialistic by nature, it is a statement that borders on the hypocritical. But even I know that not everything has a price tag attached it. Money does not solve everything. It can help make life easier but you cannot buy your way out of every situation. Where do you get off trying to fob me off by asking me "how much I want?" All you succeeded in doing is insult me.
It does not take much for you to ask permission or even acknowledge another person's ownership of something. Even if you know the person will not mind, it is common courtesy to ask - even on a formality basis.
Asking even after the event has occured allows you the possibility of salvaging the situation but to sit there blatantly and act as if you have done nothing wrong, it's just plain rude.
I think I've put up with and endured with your continued selfish behavior for quite a long time. Despite my repeated demonstration of my obvious discomfort of your actions, you have chosen to ignore me and continue with your behavior. I've tried humour and have now resorted to outright displays of displeasure at your actions. But you choose to persist with your actions. It's not even personal anymore; the discomfort is felt at a level that includes others as well.
I may not be the most considerate person, nor am I the most selfless, but I have never intentionally ignored a request made of me. Can you say the same of yourself? You cannot make excuses anymore. They are just getting tired and old.
I don't care if you are the "nicest" person because if you manage to take time away from your self-absorbed bubble, maybe you can reflect on your actions and realise that you really aren't that nice afterall.
