Here is a quick list of things that may make you a flatlander.
Your garbage bags constantly get attacked by animals and you have no idea how to fix the problem.
You pay someone else to take your garbage to the dump. (does not include a dumpster)
You will not allow you dog to go to the bathroom on your own property, but have no problem walking it down the street to go on your neighbors.
You slow down for a frost heave and then make no effort to steer away from the worst part of it.
You worry about what other folks think of your yard and therefore make it completely unusable for you and your family.
You have called the cops on someone you do not know for doing something you should not care about.
You move into an area that has been the same way for 50 years or more and complain about the things that are wrong with it.
You have to call a friend to borrow a truck for the weekend.
Your hammer, screw drivers and power tools are all as clean as the day you bought them, 6 years ago.
You get your car washed right after a snow storm when the weather is predicted to warm up.
When you lose power in the winter, you actually have food that is in your frig, spoil by just leaving it in there. Or, you go to the grocery store the day before the storm and buy more than 1 gallon of milk in case you lose power.
If you actually took the time to read the above lines to see if any apply, you might be a flatlander.
