Mercenary Girls...

Case 1:

A girl asked to join my project group, as she was weak in the subject.

I declined politely, as I was not the leader of the group.

She never spoke to me ever since.

Case 2:

A girl asked for one of my tutorials for reference. I agreed.

A few days later, she told me to simply just bring all my tutorials for her.

I declined politely.

A few days later, we spoke again. Her first line, was a demand for my answers to a graded assignment.

No "Hello! How have you been..." or "How's your day" or any of those sort of polite greetings when you're trying to ask a favour from someone. Just a direct request for me to give her my answers to the assignment.

Naturally, I declined.

No other topic ever crossed our conversations that was not a request for work.

Note: As much as they were both lookers, their mercenary behaviour was the least impressive.
