Sister, can you spare a sign of peace?

During the Sign of Peace part of Mass, people greet each other and reach out to shake hands. 

At this past Sunday's sign of peace, as everyone was turning around and greeting and shaking hands with everyone around them, Dominic, for the first time, tried to shake hands with those around him.  But it wasn't as easy as he thought. 

No one had noticed him, and he was turning around trying to catch people's eyes and hands, but no one even saw him.

Finally, jokingly, and giggling, he tapped the wrist of the woman standing behind him and offered his open hand.  The surprised woman smiled, bent down and shook hands with Dominic.
