I am under the impression.. we have no permission to enter the building, Nor do we have permission to gather during their buisness hours? So are you thinking of standing in the dark parking lot, wondering who each other is and if everyone is nice, safe and friendly, LOL? (Some of us have severe anxiety already...) And then what after standing in the dark, possibly uneasy around each other, going to a restuarant/bar or some place to party? Im a little confused.
DF, as far as ceremony.. I think it would also be a good idea to have a planned agenda (for lack of a better word), but then also allow time for anyone who needs to pray or make an offering to the event of their own a moment if they so choose. Member we are all diffrent in how we pray, grieve, process and heal.
