I remember once we had gone with some pals and a small nephew to my pal. We got into a small joint and started playing pool. the small boy said that he wanted to see us play the game so we lifted him up and placed him on a high shelf, basically over our heads, we played the game and finished and then walked away. almost 15-20 mins later did we ask ourselves where the young lad went to...and to our utter shock realised we left the poor boy on a shelf somewhere and rushed back...we found the kid crying :-(
