18-year-old son's revealing swimsuit concern discussed on Reddit by dad, who bought new swimwear.

A dad on a Caribbean cruise with his 18-year-old son, Jax, went viral after sharing his concern about his son's revealing swimsuit on Reddit's "Am I the A-Hole" forum. The father, who admits his son has "too much confidence," described the swimsuit as "inappropriate" and bought his son a new one when he had nothing else to change into. The family vacation included people of all ages, and the father wanted to set boundaries for his son's clothing choices.
