I ran a design business that closed over five years ago but I kept the same mobile phone number.
Client: We want to commission some new design work from you.
Me: Sorry, I no longer do any design work, my creative partner passed away so I closed the business down
Client: Well we were never told, we should have been told. That's good business practice.
Me: I sent three emails over the course of three months including one with some recommendations for other designers.
Client: (after checking) That was five years ago, we can't be expected to remember everything.
