What do you think I should do if I think I forged my mom's signature
Don't you know if you signed her name or not? Why did you forge her signature anyway?
I don't know if it was an honest mistake or not.
It's really bad to forge anyone's signature. You could get arrested for something like that!
I viewed it as an honest mistake.
I'm not sure the police will buy that excuse, since it's really hard to sign someone's name on accident. If this was some kind of bizarre mistake try tracking down the paper you signed and explain it to the person in charge. They may be understanding, but they may also call the police.
