First, I dress carefully, in case I end up spending a night or two in the detention centre. Second, I intensively water dozens of my plants. Third, we leave our cat enough food for a few days. (One of my friends says that her cat has become fat with all these Sunday rallies.) Fourth, we take passports and a bottle of water. It’s important, too, to clear the history of your mobile phone, as these are often checked in the detention centres.
