.I live in a small flat in a city centre. Last Saturday I got a letter from the NHS telling me to stay at home and not go out at all. That same evening I saw a mouse on my kitchen floor. It felt like the last straw. I learnt that the next-door flat had toothmarks on a box of chocolates. The next day a pest controller came and again to day and another visit on Friday. He wore protective clothing. What else could I have done?
