I feel rather too excited about the whole thing, but it will soon be my sixtieth birthday. In France this brings a reduction of 10 euros per month in the price of your bus and tram season ticket. My ticket was up for renewal on the 9th of December so I called in the transport office to get their advice.
The helpful young lady did various calculations and said:
"Let it expire, then get a monthly ticket for January, February and March, then get your annual ticket in April after your birthday. That is the most cost-effective way to do it."
So yesterday found me at the railway station buying monthly tickets for January and February.
"I don't yet have March", said the clerk.
