Hello?

OMG. There is this one person on the 3rd floor in our office that is a total snob. Seriously...this person has worked in the building for years. And every time I say hello...this person totally ignores me and walks away. Ummmm...what happened to common greetings? I keep saying hello to this person as it's some stupid game now. Fine, you don't want to talk to me? I'll keep talking to you. Let me continue to bother you. The fascinating part is that this not the first person to do this. There is another person that used to do this to me. After 11 years, I broke this person down. And now I can't shut them up. Serves me right.
