Another gesture to avoid is putting your hands in your pockets. Some nervous presenters use this as a way of keeping their shaking hands out of sight, and often wind up jingling the change in their pocket or their keys, without realizing it. Some people can't get their hands back out again and wind up spilling out the contents of their pockets as they try to release their hands. To avoid embarrassment, it's wise to empty your pockets of change and keys before presenting.
