We taught The Boy the word "tacky" a couple weeks ago. It happened to coincide with the annual over done Christmas displays in our area. Maybe next year he'll actually graps the concept since even though he says tacky when we drive by the most illuminated house, it is still preceded by an "oh...wow!" every time.
Speaking of tacky christmas displays, I drove by one this morning that consisted of an inflatable manger scene. Similar to those inflatable Snowmen and Santa Claus' that you plug in to keep them inflated. But this one was Mary, Joseph and baby Jesus. Nothing better than a cartoon manger scene at christmas.
