Sounds like something from SAW but without the violence.
There is no way I would go through with this. You don't kidnap someone and hold them against their will. It's totally wrong. As Niamh stated, friends and family would be going out of their mind with worry if you disappeared for 9 months (or be having a party whichever the case). I would not want to put them through the anxiety.
You may ask for someones help in such a situation, but not force them into doing so. It would be a hell of a lot to even ask someone anyway. They would most probably have to give up a job, their family, friends, and social life. How would mortgage/bills be paid for 9 months etc. So many things to take into consideration.
If done with the right conditions, then it would be something to consider, but certainly not under those circumstances.
It would also involve missing 9 months of Coronation street, or would I be allowed a TV?
