A shotgun is similar to a general in the army by that like a shotgun it has a trigger and someone could easily pull it and a bullet shoots out and that bullet is like a general's emotion and general is like that. If someone from the other side (not like that other side) could say something that could trigger a general and anger them or any other emotion. Another reason a shotgun is like a general in the army is that when the shotgun is out of ammo and the shotgun is empty until someone refills the gun (sorry i don't know what the word is) is like when a general gets shot and dies someone has to fill in the space or replace that fallen general.
