My first rebellious act was to buy a lottery ticket. I did it on-line so it wasn't quite as wild as brazenly going ino a shop and buying it but I didn't get struck by lightening when I won a tenner either.
Buying a birthday card in a shop was a bit scary, returning seasonal greetings at xmas gave a real sense of freedom, singing the xmas carols in my head in shops with no guilt, getting involved in local politics, signing petitions, swearing...............a lot, meeting my first apostate and realising he didn't have horns nor a forked tail.
And so much more rebellion still to enjoy.
Lovin' it!
