upset.. Today I very upset,because many things increasingly disturbing. My roommate forget to bring key,so I come back from distant place while I listened a speech,I suffered great inconvenience. This things happens already second time.To make things worse,she not only don't say"thank you",but also dissatisfy with my attidude on the phone.I just think I have a little of impatience then.But to make things worst!! when I return to classrom,the door was locked!! that's showed I can't hear this speech,I very angry. Anyway,she is my roommate afterall,meet regularly or frequently,when I set the mind at rest,I apologize to her,but I really feel wronged!!
