Curiosity - I think it's pretty easy to judge whether someone has made a stupid or a sensible decision. Examples:
1)Having sex for purposes other than procreation? Birth control sensible, no birth control, stupid.
2)Unexpectedly pregnant, useless/absent partner, too young, no home, no money, no prospects?
Abortion - sensible.
Baby - stupid.
3)Totally against abortion?
See No. 1.
Don't believe in birth control because you are Catholic?
Saying no for around 4-5 days per month, with the aid of a thermometer - sensible
Saying yes on any old day, stupid
Have three hungry children and only a fiver in your purse for the next three days? Buying some jacket potatoes, beans, and milk, sensible. Buying fags and a scratch card - stupid.
Really wanting a baby even though you are only 16 and your boyfriend is a neanderthal arse who hits you, and smokes weed all day, and neither of you have a job or a decent place to live?
Going ahead and hoping for a miracle, stupid.
Leaving him, finding a job (anything) or going to college, GROWING UP A BIT and waiting five or ten years until a nice decent guy comes along, sensible.
Living in an overcrowded one bed flat when you already have two kids?
Go on the pill, sensible.
Have a third baby, stupid.
I could go on like this all day, but in a nutshell, just grasp the simple fact that the cart must not go before the horse.
No doubt I'll be flamed or 'oversimplifying'. Meh. Don't care. I'll just say that I bet 80% of the financially self-sufficient people on MN became so by following these basic rules, and 80% of the not so self-sufficient became so by not follwing at least one of them.
