Summer nights...

...and working night shifts. I dont know which is worse, night shifts in the summer where the evenings are gorgeous and you have to go out to work, cant take a wee drink or get too involved in anything so youre not late for work. The mornings get light so early too, by the time its quite bright, it seems to take forever till the end of the shift.
Night shifts in the winter? - you come in in the dark and go home in the dark - unless you deliberately get up in the middle of the day, you dont even see daylight. No wonder I get a kind of depression during the winter months.

PROS FOR NIGHTS.
Unsocial hours money.
Dont have ward rounds.
Dont have to keep answering the phones or the door entry system.
Dont have all the visitors all shift, just at the start of it.

CONS FOR NIGHTS.
No social life.
Difficult to get a sleep sometimes during the day - amazing how many people think working nights means you sleep during the shift, the concept of "work" and "nighttime" just dont seem to register.
Wind - try picking up a few messages after a night shift - guaranteed to clear any supermarket aisle.
