Well?,......her dilema has accomplished one thing. I hadn't seen her boobs before. I think her "sprinting" down the beach would require the proper kind of safety equipment. In this situation, a bikini was clearly inappropriate for anything other then viewing pleasure(maybe matrimonial enticement?).
This is similar to people who ride bikes in flip flops, or ride to fast for conditions. I can plainly see she needs to exercise with more caution. I have no doubt she was more comfortable without all the extra gear, but there can be consequences to short cuts. Beyond that, I think she mostly wants more attention......which, she's certainly getting now. Maybe if she'd of worn a helmet cam, and posted this on Youtube. Then we all could have critiqued her careless behavior.
Maybe there is some sort of support group, I could join to help her?
