When my kids were little we were having lunch and eating some of our wonderful homemade pickles that my mother in law made.
My youngest son was enjoying the pickles so much he held one up and was going to hand it to me all the while saying "mama, will you go plant this and grow us more pickles"?
Needless to say I began laugh.
I explained to him that you could not grow pickles from pickles but you had to use the cucumbers we grew in the garden.
HE accepted my explanation and continued eating, resigning himself to just eat the pickles out of the jar.
