The Trenches!

The trenches must have been unbearable.  Having to deal with lice and rats the size of chihuahuas would be a very scaring event. Also the fact that you would at some point have to face yours fears on the front lines.  Having to leave your wife and kids if you had them, would be difficult, especially going into those kinds of conditions.  Another thing to think about is all the men going to the bathroom right where you have to walk and you have to smell all that nastiness.  Not to mention the rations, or should I say the lack of rations.
