Victor had too often in his life said No. Or rather No when he actually wanted to say Yes! and Yes when deep inside it was calling No!
In order to simplify his life, he replaced all Yesses with Nos.
It had taken him years of painstaking work to build his fortress to keep everyone out and himself in. Victor started to believe it was because of all the Nos which should have been, might have been, could have been Yesses.
And therefore, starting from today, no, from this very second, he would say YES! to everything.
