Have you done that before?

Have you dumped a girl before? Have you said NO to people before? Refusing, turning down someone? I learned in US, we need stand firm if we are right. Today I have such same feeling, I have my right as an employee to fire my boss, or the more appropriate word is resign. I need to stay firm, but meantime some place in my heart is having a butterfly, feeling should be same as dumping ex girl friend... Sorry girl, we need to move on, you are not my cup of tea, as the matter of fact, I don't like tea, I love beer...
