Tithes- Julia

What do think of the idea of tithing? I think that it is a very interesting concept- that you are a special person, better than the others because you are willingly giving yourself up. It's almost like a brainwashing technique, because we quickly realize that the reason tithes are not supposed to be around the other unwinds at harvest camp is because the harvest camp leaders don't want the other unwinds making the tithes think that unwinding is bad. However, the tithes believe that they are not supposed to be around the other unwinds because they [the tithes] are better and more important that just regular unwinds. Tithes have more of a purpose, a duty. I was trying to think of something today in our society that could be compared to tithes, but I was having trouble thinking of something. Can you think of anything that is somewhat like a tithe?
