I just have, on my way back from walking the dog with a friend, a woman walked past and I was convinced it was my sister. In fact I stopped and was staring after her, wondering whether to call out her name. Then logic took over, she’d be 300 miles away from home, she’s not left London since the start of the pandemic, she would not ever surprise me like that. But blimey, I was so worried I came home and started madly tidying up in case she walked in!
