Unluckily 'addiction' is a word so commonly heard that it does not stand out as much as it should :(
And the title ... the title. I was humming the "simply irresistible" song while searching and it still did not strike me...
...till it did :D
It was a good activity puzzle you gave me :D
Thank you for the HSBI, though I must say it was not required. It was fun trying to solve it !!!
