I couldn't do much but laugh and concede that again, as always, they're right.
I will claim many things to justify my selfies: I live alone. I work alone. I travel a lot, alone.
But United States researchers reckon it could be a sign of something rather more sinister. A study published by the University of Ohio this week suggests that men with social media feeds like mine are more likely to display narcissistic and psychopathic qualities.
It doesn't mean every guy guilty of taking the occasional selfie is pulling the wings off butterflies; just that guys obsessed with selfies are a bit more self-obsessed.
It's not rocket science, right? If you consider the preening, filtering and editing some men undertake before posting their own images online, it's little wonder researchers reckon we're breeding a generation of more narcissistic men.
To me, there's one clear antidote. You should be allowed a selfie stick only if you also have a group of friends who'll always haul you back down to Earth.
Cos from now on, whenever I pick up my selfie stick, I won't be sucking in my cheeks or making sultry eyes. I'll be thinking of my mates and their Christmas lashings. Thanks guys.
