What is one thing nobody knows about you?

This question is posed for the 27th January by my 3-year sentence-a-day diary, a gift from a dear friend. Since I started the diary 5 months ago, it’s the only page that remains blank.

And it’s not because the answer is something I wish not to put on paper so that no-one can ever find out; it’s because I don’t have an answer! What a strange thing to realize. Perhaps I need to get a secret life. 😀

Would you have an answer?
