WOW never thought about that....I am done surprising my teens, but most every trip I had to work overtime to make it a surprise....that very morning! A few times it was a teacher I had told in private about the surprise who could not keep a secret....told a counselor, counselor suspicious that an all A student was skipping school.....sigh.....he was bummed she called him down to office. Once a mailman came to door because I filed a stop mail thing, he had a customer who had been scammed by relatives and stopped her mail, he saw me home and wanted to make sure things were ok.....I had always stopped it a couple days prior in past with no interaction....it was very nice of him to worry about me, but it almost blew my cover, one child was home for a 1/2 day.....phew. I actually packed their things and hid the cases.....boys not into clothing don't notice, and since it was off season even less chance of noticing shorts missing in the winter!
Have great fun and let us know if you are successful in circumventing the box!
