Problem scenario
In the smart phone era, some people cannot get embarrassing photos removed from the internet. When you go to the gym and need to change into a swimsuit, you want privacy (so you are not seen). How do you do this without people seeing you?
Possible Solution #1
Change inside a toilet stall in the bathroom. (Showers are usually near bathroom stalls.)
Possible Solution #2
Use a towel around your body, and start to remove or put on different attire under the towel.
Possible Solution #3
Use a shower stall with a curtain if one is available to change your clothes.
Possible Solution #4
If the locker room is part of a school, consider going on homeschool. Find a way to get physical activity elsewhere.
