I found this "piece of flair" on Facebook a couple of months ago, and it made me laugh:
The girls have no inheritance, and they are oh, so poor... so they are forced to move to... gasp! A two-story house in the country, instead of living in their mansion!! Ahhhhh! The horror! The horror! And they have to go from having 25 servants to... wait for it... only ONE!! Oh, how WILL they survive??? So, poor = having only one servant and living in a two-story house. Realistic? No. Poor is... well, not being able to afford shoes that fit your daughter's feet. Or worrying about how to afford coats that fit your kids. Now that's what it's like to be poor.
P.S. A little factoid about the movie, Sense and Sensibility - they actually permed the sheeps' hair in that movie, so they would look cute and fluffy. Funny, huh?
Anyways, I digress... Second example. Friends:
Can a struggling chef and a cafe waitress make enough money to afford the rent for a two-bedroom Greenwich apartment? Uh, NO. Not realistic.
Third example: 101 Dalmations (Yes, our copy of 101 Dalmations is still lost in the Black Hole which is our house. Sigh.):
Could a composer, who has never had a hit song, and his wife, who does... well, you never really learn what it is that she does... afford a full-time maid? Nope.
So there you have it. Examples from pop culture that give you unrealistic expectations.
