Forms: complexity of the past, present and future

Now a days, filling out forms is such an easy task... If it is an online form that is. Simple information, drop down menus and auto-fillers for you computer saveys... But there are still certain situations that cause highly complex form filling situations. These are the evil forms that unfold into 4 pages of condensed questions, information inquiries and personal data. Everything must filled out, checked, double checked, and checked again, because an error here might cause total personal file backlog, and most possibly the dreaded severe consequences (i.e. not obtaining what you sent the form for in the first place).
"No problem" you say, "I will pay attention to the questions, pre-fill the form in pencil if I am nervous and away I go!"
*EEERRRRRRrrrrr* WRONG!!!
What happens if the form is already filled out for you, and all you have to do is check if the information is accurate, and make the necessary corrections...
"No problem" you say, once again, "I will pay attention to the data, pre-fill the corrected data with pencil if I'm nervous and here I go to the mail box to send my form!"
*EEEERRRRRRrrrrrrrrr* Wrong yet again!!!
What do you if the data that needs correcting has no area to make the corrections???
"Uuuummmmmm uuuhhhhhhhh hhhhmmmmmm..."
Exactly what I would say.

Forms: highly complex for no good reason.
