Fast time is getting shot at in the open.
Slow time is meetings.
Fast time is offhand encounters.
Slow time is waiting on a medevac.
Fast time is adjusting mortars.
Slow time is behind a covered position while it gets peppered with bullets.
Fast time is behind a covered position peppering the mountainside with bullets.
Slow time is shopping.
Fast time is all those other moments with family and friends.
