Max is afraid of lemons and Cooper is afraid of tomatoes!
One day, I cut a lemon in half and let Max smell it. Now, when I cut lemons he comes in the kitchen to see what I'm doing, sees the lemon and runs to escape!
Poor Cooper and his tomato fear. I bought The Vidalia Chop Wizard last year to better cut veggies for salsa. Cooper is very afraid of the sound the chopper makes but he knows as soon as he sees a tomato - it's going to happen and under the bed he goes. I put him in the backyard once, thinking he wouldn't hear it as much only to find him at the furthest point from the house, shaking in fear.
