Your Signature at 18

I went to vote on my way home from work yesterday. When I went to sign the book, the lady said my signature wasn’t the same as what’s printed. Well duh. I registered to vote when I was 18 and my signature is much different these days. Back then I wrote out all 17 letters of my name, now I’m lazy and it’s just L V-scribble and some dots. However I will say my L and V look the same as back when I was 18.
