My dad used to do this thing: he’d arrive at my house unannounced, and let himself in.
So if I was with a client, my ears would swivel around like a gazelles (ok, slight exaggeration!) and my mind would be alert wondering who had just let themselves into the house (a burglar? Murderer?), and would they come and disturb us.
I’d be distracted from my client, which would make me cross, and that too would distract me.
So I had a word with my dad. 'Please don’t just turn up unannounced, I’m working and that disturbs us'.
Okay, he said.
But he didn’t stop.
