A childhood belief about work

For the longest time, possibly even into adulthood, I thought that cart with one wheel and two handles that workers sometimes use to wheel around anything from dirt to crap to cement mix was called a wheel barrel instead of a wheelbarrow. Strange how no one corrected me during all the times I had talked about wheel barrels. Then one day I found out, I had innocently been going through the dictionary when I made a shocking discovery, I was like WTF is a barrow?!
