Bunk Beds

I grew up with a bunk bed.  I slept on the bottom and my brother slept on top.  Now our kids have bunk beds.  I think bunk beds are a good idea.  Here are my top ten reasons to get a bunk bed.
10.  It saves space.
9.  It can be a cave.
8.  It can be a jungle gym.
7.  Jumping or falling off it can introduce your children to the emergency room (I guess that is not so good).
6.  It can be a place of confession.
5.  It can be a place to introduce your kids to Jesus.
4.  It can be a pirate ship.
3.  It can be something that your kid would think up that you would not.
2.  It can be a piece of furniture passed down.
1.  What's your reason?
