When I was in the last year of primary school (1966) a boy who had always lived in the same street as me suddenly developed a crush on me. He stopped me when I was walking home with my sister and my friend and wanted me to kiss him. I refused - politely - mainly because he was just someone I had never thought of (and could never think of) as a potential boyfriend.When he realised that "No" really meant "No" he leaned over and picked up a piece of white doggy doo near his feet and rubbed it on my mouth.
A really good pick-up tactic! Not!
Needless to say, it still didn't convince me to want to kiss him.
