Answer:
There was once, when me and my friend got into an argument. Although we are together since the childhood , our financial status are a little different. She comes from a rick business background family and my father is a government employee.
When we go into an argument she hurtfully commented on my financial status and depicted her supremacy in terms of financial terms. I never knew that she though about me this way. But taking into account the duration of our friendship i forgave after a few days. She then apologized to me as well.
