Naked in the neighbors yard

My boys never wear clothes. The second they walk in the door they strip down to their undies and it's a fight to get anything back on them. It is a common site to see two small boys running around our yard in undies and crocs. I don't mind them being half naked in our yard but it is distressing when they go visit the neighbors in this state. Peyton came in the house tonight with tomatoes the neighbor had given him...while in his undies. They love to do yard work with the elderly man next door...in their undies. They hang out with the teenagers next door...in their undies. And of course if you are already half naked outside why on earth would you bother to come in the house to pee for god sake? UGG.
