Pear shaped

A year ago I was sitting somewhere. It was a hot and sunny day (about 35 °C), Im sitting, reading a magazine, a fan is blowing right into me. There's this lady with her little kid sitting 2 m away from me, all sweating, and complaining about the heat. So I offered her to set the fan to blow into her so she could probably stay alive. So I turn the fan, she is very thankful, Im back to my magazine, she is now quiet, life is good again. Suddennly she is talking to me again asking me:

- "Are you spanish?"
- "No. Why would you assume that?"
- " Oh, just because of your funny accent" (laughing)

Im thinking, what a bitch? I give away the fan to a stranger and her ugly kid and what do I get ?! She is making fun on my English?! Ok, there you go.
So Im asking:

- " And are you greek?"
- "No, Why would YOU assume that"
- "Oh just because of your fat ass"

You can guess who was laughing at the end. Anyway She took the kid and left all shocked and upset. So I had the fan back, there was nobody around... NOW life was good all over again.
