Embarassed party of 1!

Since Sam was born in May of 2006 my husband and I have argued over when he'll go to school... will he go when he has just turned 5 and be the youngest in his grade or will we hold him and send him when he's already 6 so he will be the oldest?  My husband and father have both convinced me that holding him is the way to go.  I'm not sold on the decision, but since they're both early summer birthdays and went through being the "baby" of the class, I caved.  SO I did get him to agree that Sam needs to go to a good PreK program next year so that he's not bored and has something that is consistant in his life.  We have called every preschool program in the QCA getting information, schedules and pricing.  While we're on the subject of pricing, let me mention quickly that they are charging more for a preschool education then I pay for my energy bill every month... it's CRAZY.  Sorry about the tangeant- on with my story; so on Tuesday night we went to Lourdes Catholic School for the early childhood open house... as we were leaving we had stopped to chat with some people when I noticed Sam examining the HUGE crucifix hanging on the wall (very lifelike I might add)... Let me stop here and explain the religion status in the Munn home.  We are Christian, religious people, that were all baptized in the church and believe that there is a wonderful power greater then us.  We are also unfortunitely a family that has way to busy of a weekend to get to church on a regular basis.  We read our children Bible stories and discuss the true meaning of Christmas and Easter... Okay, now on with the story... So as I see Sam staring at this crucifix, I start to worry that he's going to say something inappropriate but before I can even lean in to explain, he loudly asks "Mom, who's the guy and how'd he get all those ouchies?"  MORTIFIED is an understatement...  Although I was embaressed at the time, as I've thought about it, I realized, he's 4.  I don't think he needs to know what a horrible event that was in all the details... All too soon he'll understand why that "guy" got all those "ouchies" but for now I just stuck to the response "Jesus got all the ouchies because he loved you"... beautifully enough that was all Sam needed to know.
