I was a pall bearer at a WW2 vet's recent funeral....he was a 32nd degree Scottish Rites Mason, also....he was honored by having both ceremonies performed at the interment.
I've participated in several military funerals, but have never seen this happen:
The two soldiers folded the flag properly....then, the one who was holding the completed and folded flag, turned to the family, and said "Would the family member who is to receive this flag, please remain seated, while the rest of the family, please stand."....the oldest daughter remained seated.
The soldier approached the oldest son, and promptly handed him the flag....everyone was astonished.
I've googled this, but none of us old farts have been able to figure this out.
WTF ???
