All Comes Down to Motive

Sam and Simmy just finished watching a movie called, "The Oxford Murders."
"The only perfect crime that exists is not the one that remains unsolved, but the one which is solved with the wrong culprit." -quote from the movie.
"I have been really struggling to understand the 'moves' people make to repay the perceived wrongs that have been done to them and I have decided that all behaviour has a root in some type of motive."
"That's pretty vague," Sam said.
"How many people have you and I met in life who create a 'oh, I'm so poor' scenario and then when you've known them for a few years... you find out that their definition of 'poor' means that they may have to cash in an R.R.S.P. to help their daughter pay for a wedding... just an example. It was that way with Northerner and 20th Century free woman."
"What?" Sam laughed. "Who is that again?"
"You know, that couple we used to go to church with who had themselves an awful itch when the woman who held both of their investment portfolios' started attending the church."
"Oh, yes," Sam was highly amused now, "we had no idea they had investment portfolios' until they confided in us about how uncomfortable they were with her attending the church and having that information."
"I was kind of angry at expecting everything free 20th century woman after that," Simmy said.
"Oh, you've spent your life being generous to the point of bankruptcy. You're just angry you gave some of your resources to her because you later found out she had plenty and was just willing to take what little you had," Sam ruffled her hair.
"Um, yah, that always makes me mad. Seriously, what was her motive in trying to create this persona of poverty?"
"Um, yah," Sam mocked her back, "she wanted to keep her money exactly where it was."
"My parents raised us to stand tall and deal with it when things are tough... and eat oatmeal. It's cheap!"
"People don't exactly perceive hard times the same anymore, love. You'll have to realize that," Sam said to his idealistic wife. "Most people would live in a cardboard box as long as they don't have to give up their cellphones and, of course, the cardboard box must be within Wi-fi proximity."
"So, wi-fi...ght it?" Simmy imped.
"Funny, very cute," Sam said with his drone tone.
