Did you ever forge your mum’s or dad’s signature?

I never needed to, but if I had, this comment, I read this morning, would have come in useful.

I remember the first time I asked my dad to sign something for me in high school. He shook his head and said, “If I sign this, you’re going to have to learn how to forge my signature. If you sign it from the start you’ll be able to sign whatever you want and they’ll never know.”
