Have you ever accidently flashed/mooned someone?

Today I almost did. I went to the public swimming pool and I was wearing a swimsuit that is more low triangle cut (but it's not like I have a lot of chest so...) and while I was getting out of the water, I didn't use the stairs and propelled myself up with my arms out of the pool. Only to realise at the last second that I was probably showing more than I should.
Worse, there was a man looking directly at me. I was freaking out to the point that I later showed what I did to my mom and she assuredf me that the most you see was a bit of cleavage and to relax that I didn't flash anyone, and even if I did, it's a swimming pool, it can happen.
