The World Doesn't Revolve Around You

So I'm exiting the MUNI station and I'm excited about going home because:
1. I'm hungry
2. It's been HOT all day
3. I'm tired

Minding my own business I walk to the stop sign and wait for the lights to change. I just hear a snippet of some girls, (I say this politely because I'm nice like that), saying "stupid b*tch... with her f* container store bag ignoring us when we pay her a compliment." Then it dawns on me. They were talking about me. You know, when there are maybe 20-30 people around you and you try to get their attention by saying "hey lady!" don't expect every woman to turn in your direction.

I was pissed, but I ignored them. Then they come up behind me and touch me on the shoulder and "politely" say:
We like your hair!

I say, "Why thank you..." and walked home my merry way.

What is wrong with people? Just for your information... the world doesn't revolve around you.
Thanks!
