INSTRUCTIONS: Whilst in Scotland, I couldn't help but notice that along the roadway, there were signs posted, simply saying, "Thank You". These signs were as regular as stop signs, or speed limit signs.
I asked my grandfather,"why are there Thank You signs posted?"
He replied,"Well, it's thanking us for driving safely. Also, if you can't read the sign, you're driving too fast."
He may have been telling the truth, but I preferred to interpret the sign at face value, like a bumper sticker that says, "Don't be a jerk." Just "Thank You".

Make a Thank You sign, and post it appropriately.
Thank you.
