Yah, but that's a HUGE gap between 29 and 20. It doesn't seem like it to you, but trust me, when you teach as long as I have, you see that things only a few years old don't "connect" because of when people grew up. The ONLY president most of these kids really have ever been aware of is Bush.
I know what you mean I am 21 and am surprised at how ignorant people my age are about things that happened from 1990 on back.
