Refreshing all the time except a little actually very little sleep after dinner. Pretty much nil after a week!
Dinners are relatively quiet. Area around you is dark yet very active. Distant noises of test rigs are pretty evident in night compared to morning. In fact a little out of place is the combination of night and plant work. You perceive surroundingsdifferently when you see others pretty much done for the day even if it is hardly four in the evening.
