I went to see the new Harry Potter movie, and a little bit into the movie, I needed to use the restroom. So I walked out of the theatre, and on my way out, I decided it was time to use the men's room. I walked in there at the same time as another guy, but he was only 10 years old or so, so I decided to keep going. I didn't want to look weird when he stepped up to the urinal and I went in a stall, so I pretended that I just needed to wash my hands. When he left, I went in the stall, did my business, and left.
That's kind of all there is to the story =/ I just felt really empowered because nobody questioned me going in there or being in there, and I felt like sharing.
