So i attended a christian school function last night but 45 minutes of it was?

the pastor's wife giving a demostration about christ in the history art and she gave a slide show of different art in culture about Christ. The school function was "family art night" and all the kids were there. kindergarden to 7th grade. It boggles my mind to attend things like this. It's 7:30 at night on a wednesday and so many families and parents are sitting through this for 45 minutes with kids bouncing in their seats. I'm just confused why parents enjoy activities like this and go through so much time and effort just to go. If i wanted to look up christian art, i would have done so on my own time and effort.
