I always find people calling me Katherine is so strange! In a good way, of course. Over the years it's shortened down to 'Kat' for all save my parents. Someone has to call me Katherine lest my name die out and be forgotten! And it's a good name!
Wolfred is brilliant. Jack is actually a name that's stuck with me for a long time. My grandad was a Jack, and thus in his honor if i should have a little boy in the future he shall be blessed with that name too!
