Take four kids all zipping in (and out and in and out) ... two from California, one from Virginia,and the one who remains at home. Add in friends and spouses.
Toss in a health crisis with the grandmother in Florida (not too serious but nobly being covered by the Mississippi sister- we owe her- big time).
Toss in last minute things like tree decoration (Christmas eve), last minute shopping, the different hours kept by the time zone warriors and a million other details too mundane to mention, but all of which take time...
Tree, turkey, presents, family!
