I thought it would be an ordinary Saturday—just a quick shop at Sainsbury’s, a cup of tea with my neighbour, and then back to my quiet flat. But everything changed at the checkout when I realised I didn’t have enough money, and suddenly, the world seemed to close in on me. That day forced me to confront the loneliness and helplessness that so many older people face, invisible in a society that rushes past without a second glance.
