Invading Privacy

Have you seen flies mating yet? Well, if you have not seen it yet, here it is! I was in my mother's yard taking pictures of her beautiful flowers when i happen to turn my back and saw these two flies, mating. I was laughing because they did not really flew away, instead they stayed and continued what they were doing. So i hurried and took the chance to take some snaps of them. I was thinking if i was invading their privacy or not. And if i post this photo, is this considered as pornography or what? lol! Anyway, i am proud of myself in the end though because it is very rare that you can get a good shot to a very rare scenery like this.
