So, on the way back Nina was desperate to pee but she also noticed that my windshield was really dirty from long drive and bugs stuck on it and she had an idea how to clean it as I was out of liquids for washing windows ...  We had to stop somewhere and you wouldnt believe where we decided to stop, risking that she would be seen and all the other problems we might have if anyone seen us ... It was funny and challenging but we loved it ...
