I fully understand! I worked at Wal-Mart for 4 years and I recall giving myself an ultimatum to either be out of there by a certain time or shoot myself. XD
There is no reason to stop. Once you take out one person you minus well keep going until you go down. Otherwise it is look outside of a cell and resent being alive.
So what do you do at McDonalds?
At Wal-Mart I worked in the Electronics Department.
Haha, that sucks man.
