done that myself - the hand has been held out just a fraction too late and ive missed it only realising milliseconds later and then shaking the hand. with kids id say this was the result.
one thing abbot did before he was prime minister won me over and gained much respect from me was the time he was in a school and he was sitting on a kids chair when a child came up to him to shake his hand. abbot stood up as he took the kids hand
