Ronan's version of potty training

so ronan is doing well at potty training...but...there's always a snag. yesterday at the park i was sitting over by the play structure when i looked up and saw ronan way out in the open field with his pants around his ankles...peeing....in front of many onlookers. i screamed and ran to him and told him that he needed to not pee in front of people and that i had brought a bottle for him to pee in. so about an hour later i look over at the bench with our stuff on it (right BESIDE the play structure = lots of kids). there is ronan peeing in the bottle. AHHHH!!!! so i run after him again and he says "i peed in the bottle!" what do you say to that?! sorry parents for my naked boy. :)
