Well, unless you posses a superhuman ability to walk around with your eyes closed sometimes it is simply impossible not to see some breasts against your will.
You're overthinking it :) My original comment was just a reply to a guy who said "Bali used to be great, because women used to show their breasts", and I was like "believe me, some breasts you'd rather not see". I really do not care why women show their breasts, I just do not want to be traumatized by it :P
