Is this a new sport? You will have to ask JORGE. We were leaving the same day as Jorge was arriving. He told me he would be wearing a yellow cap and to wave to him through the glass at the airport. I spotted him and waved and he came up to the glass and kissed the glass. Barbara waved. It was so cool and made my day. It was a long trip home and I laughed every time I though about being kissed through the glass by a stranger.
