My brilliant idea

When I went to the public pool the other day, I started thinking how I could hide my wallet and keys so I could swim without anyone taking them.  Suddenly, I came up with a brilliant idea! You bring a bag and staple a musical greeting card to the opening flap.  (Obviously, you have to get a bag with a flap.) Then when a theif opens your bag, a nice little tune will play and hopefully deter them from digging around in there.  Cheap and effective!  I’m sure this will take off at pools and beaches all over the world now.
