No Touchy!

Sorry for the lack of updates. I have been technically challenged recently. But Not to fear! I have a new computer! Thanks to generous supporters, I was able to make a laptop purchase. You guys are great! I will try to use it more often....no more excuses.
As I was travelling this past week on business, I observed a wonderful mom, with her two kids. One was a little girl of about three, and the other, a boy about five or so. Mom decided to stop prior to entering the store and give Missy some candy. As she unwrapped it, I noticed the boy (typical) searching in the trash can. As he grabbed a straw from a well used container of cola, his mom, steered his hand away gently, and reasoned with him that it was not acceptable as one could get some plague that might be fatal. As she went back to her original task, the young man (first born male child you know) went for the cup again. Again, mom wisked away Johnny's hand. Undeterred by this minor setback, Johnny went for the trash can lid to see what would happen. Another reminder of the unsanitary and dangerous nature of this venture. Then, in total defiance, Johnny began to touch everything on and around the trash can, and looked at mom as if to say, " I will do what I want to do!".
Okay....for all you parents out in blogger land...here's the question. How would you handle this?
a. not make such a big deal out of it, wash Johnny's hands real good real soon.
b. not make a big deal out of it, let him play in the stuff... Don't clean his hands...let Johnny get sick as a
pooch and remind him of his misconduct that day.
c. give Johnny a big swat on the behind, and let him know that you mean business
when you say NO and that you care very much about him, or you would not
discipline him at all.
d. give Johnny a good talking to, using large words and phrases like "pathogens"
that he does not understand.
e. none of the above.

Give me some feed back on this one, and I will write more later. Jory
