Several weeks after his birthday, I stopped by my sisters house and my 7 year old nephew greeted me with, Thanks for the Sea Scout Signal Whistle you gave me for my birthday! Its the best birthday present I ever got. Thats great, Did you learn how to pipe any signals on it? Oh, I dont play with it, the little guy said. My mom gives me a dollar a day not to blow it during the day and my dad gives me five dollars a week not to blow it at night.
