My parents are the same whether I travel from Attu Island to Caroline Island or from Caroline Island to Attu Island.
The mother sandwiches an 8 between the highest numbers. If she replaces 8 with 92, she still remains my mother but becomes quiet.
The father sandwiches a 1 between the halves of the highest numbers. If he replaces 1 with the smallest number, he has performed.
Who are my parents?
