Oh, to explain...
Our high school football team had 2 Tongans, and 2 Samoans. On paper, you'd think they'd gell like bread to butter, all 4 lineman.
But no, they kept to themselves, having more friends from other countries than to each other.
I was sorta the "mascot" for both tribes. Being about 5'5" and 111 lbs., while the smallest Tongan was close to 6'1" and 300 lbs., they loved the fact I played OLB, strong side, and often pass rushed.
They appeared to have different cultures and values, yet only 300 miles apart by beeline distance (some course adjustments needed to account for prevailing currents and trade winds)...making it closer to sailing around 500 miles to go from one island to the other.
