On Friday afternoon I have to attend a meeting in Villenave d'Ornon.
Villenave isn't very far from here, but the best way to get to it is on the rocade, the peripheral motorway. OK. 20 mins and you're there.
Except coming back on late Friday afternoon is likely to take MUCH MORE than 20 minutes because of the traditional Friday traffic jams.
It's here that public transport comes into it's own.
I'll take the bus there and back. It'll take longer, but it'll take the same amount of time both ways because the bus uses a circuitous route through the suburbs. And I can read instead of fretting.
