Re: Shifts
The idea is to never let the flame go out, so yes, it would be all night. However if you need to sleep (most of us do) I suggest a candle contained in a heat resistant container (you could get a 'jesus candle' from the grocery, walmart, etc if you wanted and ask your Priest to bless it for your shifts) and keep it near you but away from anything flammable. It will burn at Sundown on the day of your shift until sundown the next night. I like the tall candles in a candle glass as it will burn that long and will travel with me. If I have to go out, I can take it with me, sit it on my desk at the office, etc. At sundown the next night, someone it beginning their shift so in essence you are 'passing the flame' to another.
Thank you for taking the shift. If you want to give up the second shift, no problem, just let me know. Also let me if for any reason you can take a shift at all. This is flexible.
