As a kid my favorite part of Purim was shaking my grogger at the mention of Haman's name during megillah reading. As an adult it seemed uncool to shake a grogger .Instead people would stamp their feet at the mention of Haman's name.
More time has passed and I have returned to using a grogger at the mention of Haman's name during megillah reading. It a lot easier than stamping my feet and much more fun. More kids shake groggers than adults but I feel the grogger shaking is keeping me young. It also helps me pay better attention during megillah reading.
