Alright. Please treat the term 'friend' more seriouly. Being your friend does not mean that you can belittle me. You still have to take your promise and respect me. I mean, I can accept jokes on me to a certain extent, but I am not that kind of person who is indifferent about others' uncaring. You dare not to treat me like THIS, when you ask me to fulfil your demand but in the end you just say 'I can't come" without an apology. I put efforts to meet your demand,  no matter large or small, and I believe I deserve your apology right?Huh?

It's a pity to know that I have a friend like this. Well, it's not the first time. The issue is small, maybe, but it has created an adverse impression. Anyway, what I would like to say is, be responsible for what you have said. I am not responsible in helping you. You know now, I have to explain to another group of people about your absence. What is the purpose of THIS? I do not need to bear things like this originally. What you have done lower my creditibility to that group of people. Okay, then you just say a word on it and withdraw from it. THANKS A LOT.

I can help you if you really want something, and if I can afford to do it. But please, I pledge, think before  you ask me to help you. You may eventually create problems to me. That's it.
