Palm Sunday

I wonder why in some Evangelical churches kids get to have palm branches in Sunday School while adults don't? Do we assume that our children need object lessons and something tangible to understand a spiritual truth while we as mature adults can focus on the spiritual without any help? We might be giving ourselves too much credit. Or, maybe, we think adults will be distracted by something as green as a palm branch? I dream of a day when I can be in a crowd of people walking to church all carrying palm branches. I think it will be very cool.
