Do you agree with this acquaintance's thoughts on the "germ" situation?

We had a family gathering at the lake on Saturday. We also invited a good friend of my husband’s, Dean, and his wife, Cathy. There were kids everywhere. Dean and Cathy walked up, talking amongst themselves and I heard Dean say, “Look! There’s more under the table!” That was funny!

We cooked ribs and beans and corn on the cob. I snapped several corn cobs in half for kid sized portions.

My son gave their one year old a cooked half cob. Mikey turned it into a play toy, which he would sometimes munch on. At one point he was sitting on the ground, banging the cob on the ground, then taking a bite, then rolling it around, and nibbling some more. He’d crawl away for a while, then come back and eat some more.

Cathy was just horrified. She’s very prim and proper and she kept talking about the “critters and the germs” on the ground.

No one else gave it a second thought. Would you have just ignored it, or just let the kid go on with what he was doing?
