Hand signals can be confusing for a farm wife; sometimes I feel like I'm supposed to read Popa's mind. It's the worst whenever I'm the one in the tractor; what do all the circling motions mean? Turn the steering wheel right or left? Move forward or stop? The wave, back and forth, are we finished? The one signal I do know is the disgruntled frown; I just don't know, but I can't read minds.
