| In 20 years, my life has come full circle, 360 degrees for real. People often say 360 degrees when they mean 180. They say full circle when they’re really talking about a semicircle. I've never experience this, is it common for some group of people to use 180 to mean "the same" vs "completely different"?
In the midwest, to do a 180 is to go in a completely different direction, and to come full-circle is to return to where you were after some long journey.
