As kids my older brother and I would set up little plastic army men on two sides and with BB guns blazing the battle would rage on until the last army man left standing. The loser ( me ) got to do all the chores that day. Much to my late dads dismay we would play cowboys and Indians on his pool table. Cowboys were solids, indians stripes. My older brother would take position on one side of the table, myself on the other and we would sling balls across the pool table at each other until the last ball left standing. The loser (me) sporting smashed fingers, did all the chores that day. Some of us played cops and robbers as kids with toy weapons. We grew up watching it in our drive ins and movie theatres, Sci Fi's, horror flicks, murder mysteries.
Deep down where nobody wants to go violence, death and destruction entertains us...
...and my older brother was lazy...
