He replied,"It was id ten error."I Didn't want to appear stupid,but nonetheless inquired,ten t error? Whats that..in case i need to fix it again?Harold grinned...."Haven't you ever heard pf an id ten t error before?"No i replied." he said,"and i think you'll figure it out."So I wrote down ID10T,"I used to like Harold.
