watch out for overweight luggage

I bought too many books in Paris, no question. That happens every time, and is inevitable.

And yes, my luggage was 2.7 kilos overweight. The penalty for that? 100 Euros! They let me open my luggage and take some books out. I chose 4 books that looked like they might add up to around 2.7 kilos, and put them in a plastic carry-on bag.

Despite my general incompetence with the metric system, those 4 books weighed exactly 2.7 kilos. Not a bad guess.
