I think both are equally embarrassing. I've walked in on some people, but that was at my parent's workplace, and there were so many stupid Asian girls who are so retarded, they didn't lock the door. And it was a public restroom, for crying out loud. How dumb can you be?! I've walked in on little kids too, but that's because they're too short to lock the door, so that's excusable. My mom also walked in on her friend's old mom. My mom is an airhead, that's why.
She saw her go in the restroom, but for some odd reason, my mom couldn't comprehend that in her brain and just ran in there. The old woman must've had a heart attack. We were visiting my mom's friend's house so that's why she didn't lock the door, 'cause it's her own house. I've never been walked in on because I always lock the door no matter what.....
