Suprise me

As i wait my next flight, i decide to write. Frans told me that jamsostek open recruitment. So i take a look at the website to find out what i need to prepare. Than i see the statement told,'agree to not marry on contract period'. Than an idea come up to my head, 'what if i want to get marry?'. This idea kind of shocking me,because i never think i want to get marry before or at least i never think marry will be one of my 'thing' to not apply for a job. Yes i have crush with a man on my office. But we arent even a close friend. I only can say 'hi' or 'goodbye'. So, why i should think about this 'not allow to marry' thing?
