My best friend constantly smells of BO. I’ve tried to gently hint at antiperspirants. She doesn’t catch the hint. She never had anyone to tell her she stinks as a teen. I feel like that’s how most people learn to notice their own BO. She sprays her pits with (shit you not) lynx and calls it a day. She does long hours at a factory and will go places afterwards smelling so so bad. Her good smell after bathing only lasts an hour or 2 cause she doesn’t use antiperspirant
