Little Helper

Benjamin loves to help vacuum! Which is a great thing don't get me wrong but I wish he would wear clothes while he does it. Yep, he likes to vacuum after bath while wearing only his night-time underwear. He doesn't even want to wear his pj's. I have no idea why. Does anybody have an idea or reason why? I will just enjoy the help and the black mail later (vacuuming without clothes while only wearing underwear). Some things are just priceless, aren't they?
