Imagine other decisions being made in the same fashion.
1. So you apply for a job and if you get the offer, you have to take the job. (OK, play along it's not that far off what actually happened.) You have no idea what the job role is, nor what you'll be paid, how many hours you'll have to work, who your boss is, nor what your promotion prospects are. But you apply anyway and "hope for the best" or convince yourself that "it will all work out".
2. So you buy a house. It's a huge commitment. Depending on the mortgage you take out, it's a 15-30 year albatross around your neck at least. All you know is you're sick of living in rented accommodation (fair enough) which is cheap but you don't like the wallpaper and your landlord is a bit of a second hand car dealer. You spend ages humming and haa-ing about whether or not to buy, (two years to be exact), jump in with both feet and..................buy a house you haven't seen; no idea what repairs it might have, what the local schools are like, and where you'll do your shopping. (Or if you'll have any money left over after paying the mortgage to buy food, for that matter).
3. So you go on Blind Date (see below) but Cilla (again, play along - in my world Cilla lives forever) forgets to tell you that there is no getting out, and you'll be required to marry your choice at the end of the show. Your three options are behind a curtain..................... Enough said.
Anyone?
