NL - gone today
FL - gone last week
BF - gone
IG - gone
TD - gone
HL - gone
LT - gone
LP - gone
CS - gone
KS - gone
QX - gone
Da - gone
MM - gone gone gone

It was a beautiful day, I didn't have to go home, I didn't want to go home, but that was the only thing I could make myself do, so I went home.
