English, you must live in quite an urban area if you are able to say "I wouldn't choose to go more than a half hour drive from school for social reasons"...
From my own home, I am a 20 min drive away, which means I would be pushed to get there in half an hour, if I was in the shower say, or still had younger kids...
If I go to our nearest supermarket and am half way through a weekly shop, I am at least 40 minutes from school...
If I go to our nearest town, I am (just about) half an hour away if I am driving and traffic is OK; but I am 45-60 mins away from school if I am using public transport...
The nearest city is over an hour's drive from the school, in good traffic...
If I go to our local hospital for my physio appointment, I am 40 mins (in a car) or 90 mins if I have travelled by public transport...
Last week I went to visit a friend who had been transferred to the nearest specialist hospital unit - that was 90 mins drive from school...
The nearest maternity unit is over an hour's drive frm the school...
Several of my friends live three times as far from school or towns...

Doctrine, with most employers (certainly local authorities, who are the biggest employers in most areas) dependents/parental leave is only allowed for serious things - broken limbs not vomiting, for example...
